I love this video. Great explanation and recording of the examples. Thanks so much!
Thanks, part 2 is up finally!
Nice video man thanks for taking the time and for putting this info out there. Great job!
Part 2 will have even more great info!
Great video. This is EXACTLY what I was looking for.
When there’s trouble call DW
nice comparison report. It will be nice when you go over candidate 1-6, you can have a table below to show the rating from previous candidates. For example, while going thru rating of no 3, you can show a half-filled table of rating of no 1 and 2. This will make it easier for viewers to see if this is better than the last 2. Once again great job and keep that coming.
Thanks! I’ll have to do that comparison table in part 2. Thanks for the tip!
Been a while man. Good to see you back at it. Great video! Can't wait for part 2. For the record, I'm mostly a haunt and props guy with occasional side projects involving Universal, Disney, and of course Mortal Kombat! Hope all is well and you're enjoying hockey season. 🤙
It’s that time of year man, unfortunately I had to go out of town for a funeral, the shop is busy & it’s the holidays, but ya know life of a dad lol thanks for watching & yea part 2 is gonna be a fun one! Go bruins!
@@Darkwingdad definitely hear ya there...life of dad. Never a dull moment...Go Bz.
Very informative video ❤
thanx for sharing bro, i'm in the movie making industry and know its alot work throwing a short movie together. i do what you do as hobby, thanx for sharing your time and energy
Anytime! Editing is addicting but exhausting I feel ya!
I've had good results with the Rustoleum 2 in 1, but a lot of that is availability for me. The Bondo looks really good, eagerly awaiting the final results!
I just can’t get past the wait time and the gummyness/build up on the sand paper. 90% of rustoleum users are strictly bc it’s so available. It does do a good job filling there’s just other things that drew me away from it, things you don’t realize until comparing multiple brands. I do appreciate the input & thanks for watching!
I agree...Bondo looks like it might be pulling away from the competition...place your bets...lol
Magic.. it's all black magic!!! Just like when the camera stole my soul!!
Not sure if you have ever tried sanding rust opliym when it is dry but not cured. It is a weird semi rubbery consistency. It will gum tour paper instantly but then you can kinda polish it. Works amazing to get real clean details. You can sculpt and carv the paint to get super crisp detail and control of texture. Very delicate and finicky but if patient can yield incredible results
But why bother when you can use a solvent based primer that fills better, sands easy & dry & ready in 15/20 minutes not hours like crustoleum?
Great Video DW, bad timing! Just left HOME Depot yesterday with 2 cans of Rust-Oleum filler and primer yesterday😬 . Still good info moving forward👍😏
Just needs more dry time my man, if you have any questions just ask!
Glad to see this video up, I was really anticipating it. I agree with everything you rated, except for bondo, only because I haven't tried that one yet so I can't say. Question though, you really turned me on to using etching primer first, so you still do that? I really like the way the filler primer lays onto it.
100% on the etching primer love it and serves an essential role. Watch next weeks video about bondo filler primer ;)
Great video.
Thank you for this info!!!!!
More to come!
That mask does not prevent anything because you are still smelling the primer. You should use 3M filtered mask. If you smell something, it is time to change the filter.
It does have a filter in the front & notice I have an exhaust fan & filter in my booth pulling the fumes out. Yes a respirator is the proper ppe but in this case this is better than using nothing as many often do.
In the UK carnt get the bondo spray lol
Have you used Iron Armor filler primer from harbor freight tools? Its only $5 and the reviews on theyre site look good but Id like to hear your opinion.
I’m testing it soon. Haven’t tried it yet
You might want to use a cartridge respirator when spraying this stuff. Those N95 masks might be better than nothing, but they aren't designed for use with spray paints.
I normally do, this was quick tests here and there. Go through all my videos I wear 3m respirators
Would you mind recommending? I’m painting a bowling ball chrome silver (not to be used for bowling). Which primer would you recommend if I get a colorful bowling ball? It’s cheaper ($50) as opposed to a white one ($90). Do you think it’s worth it to get the white bowling ball or can I get the coverage for the cheaper colorful ball?
Bondo is you can get it. If not check out upol primers, they are fantastic!
Bondo Grey Lacquer-Based Sanding Primer MN 0720 is no longer available at ACE, it is being replaced - its a shame after good reviews the manufacturer discontinues??
That’s really disheartening to hear. Such a great product
bondo filler primer has been discontinued do you have any recommendations for replacements?
I am doing a volume 2 test on this. Filming has begun! Check out the video to see the line up!
I feel like you were a bit hard on Rustoleum. I don't experience any of the issues you had with the product. I would suggest getting a smooth drywall sponge, press lightly, and not think of it as sanding/removing the primer. Instead think of it as if you're polishing the 2 in 1. It'll actually shine up, and be super smooth. As far as control/spraying issues, that could be technique, spray distance, or even climate. Who knows? It's like filament. Results may very. I can't say your opinion is wrong, if it's true to you. I can only say it's different than mine.
It’s a test so each one is ran through the same test. What it shows is rustoleum is a more delicate filler primer. Its show variance as the other 4 primers had little to no issues. More sanding tests will be given in round 2 with different media and grit. What I can say is you don’t want filler primers wet sanded or smoothed so much to where it creates a sheen and can reject top coats. Additional tests will be conducted in part 2 but even with a sanding sponge and inteface pad both rustoleums gummed up and we’re gouged by 220. I noticed the rustoleum needs different techniques that I mentioned in the video & I’ll highlight them in test 2, thanks for watching!
I've built a mark 17 suit, and I'm currently printing a mark 2. I haven't come across the topcoat adhesion issue. I definitely dont wet sand the 2 in 1, but I believe the manufacturer recommends it. Ive seen others wet sand anyway. Maybe, these are all techniques you'll test in upcoming videos, and if you come up with something interesting I'll definitely give it a try.
Hi sorry if this is an obvious question but can you sand the filler primer when it's dry? Because I made a death eater mask for Halloween and was hoping it could be lightly sanded when dry.
Cheers
Yes you can sand the model, apply the filler primer & once dry repeat that process until it’s smooth. You want to change the grits of your sand paper each layer you do. For example- sand the model with 80 or 120, than sand the primer with 160 or 220 and after you apply more primer sand with 220,320 up to 400 grit.
I know rust 2in1 says 2-4 hours, by i swear it only sands well for me when I let it dry for 48 hours :)
Lol ironically in my part 2 I state & show how long it takes for it to dry. 90% of the time when people have frying or reactions it’s all derived from rustoleum. I’m not saying it’s total garbage but it’s finicky & lots who use it do not wait proper times I guarantee. I see people loading this stuff on after an hour…that’s just asking for trouble. IMO a filler primer should not be so temperamental, primers should be the easiest part of painting.
showing the product labels for more than 0.5 second would be a good idea

Based on your reviews I bought 3 cans of bondo filler. That was a huge mistake. The nozzle is the worst Ive seen and it eventually became a dripping mess. I thought it was me but a quick amazon search revealed the same.
What temperature were you using it in? I would contact 3m, I’ve literally never had an issue with bondo filler primer
@@Darkwingdad im using at 70F . A bunch of negative reviews on amazon saying the same thing.
Btw. Do you wash after sanding the putty before priming? Love all the Starlord stuff.
@@jack91522 I would contact 3m, if it happened with all 3 that’s definitely a manufacturer defect
How does Halfords filler primer compare?
Hey joe I’ve never used it but something I may look into!
Can I use any of them to paint my plastic mirror from my car?
100%
Why do most come in gray? Isnt it easier to paint of its in white?
Gray is the most neutral in the color spectrum. Primers in white & black will heavily affect top coats tinge & hue hence why most primers are grey. White & black are both too harsh in hue that’s why they aren’t made. The only primer that’s easier to paint on is a solvent based one, color is irrelevant.
In your “defense” you’re not wrong about mentioning color. Often times people who are painting gold or metallics would benefit from white and many times mix & match enamels and run into adhesion and curing problems. The best thing to do if you’re wanting color variance is use a white or black matte or satin enamel as an undercoat. Many people do gloss undercoats which just contributes to orange peel & potential improper curing & warping.
You've said multiple times that the rustoleom 2 in 1 is water based. The product spec listings I've checked on different websites says it is oil based. If this is oil based doesn't that mean I can't use acrylic paints on top of it ?
So recently rustoleum did in fact change there formula & the new 2 in 1 (260510) is in fact oil based. The filler primer used here is there old water based formula. So if not fully cured it will definitely create adhesion issues with acrylic paints.
Do you know if there's a way to tell which version is which? I literally dumped like like 8 cans of this stuff into a bunch of very large models and I'll cry if I ruin everything when it comes time to paint.
@@Darkwingdad what do you think I should do? I have a bunch of models primered in the Rustoleum 2 in 1 and nothing but acrylic paints. I researched doing a barrier coat and found mixed ideas on this. That1painter claimed on his website that primer is different and its ok to put water based primer on oil based primer. Other websites say oil and water is a no go 100% of the time. I was thinking That1painter might be right because supposedly the reason acrylics crack on oil is because the oil off gasses through the dry acrylic. But Rustoleum 2 in 1 dries so fast I would think this might not be an issue? Another thing people say is the glossy nature of oil is problematic for acrylics but as everyone knows the 2 in 1 isn't glossy. I dunno *bangs head on wall*
@@Darkwingdadsorry this was my other account. So yeah... just got off the phone with Jesse H at Rustoleum. He said the 2 in 1 Filler primer has always been oil based. No formula changes. The good news is he said that with this primer you can put water based products on it and I could even do laquer if I wanted.
@@bangtizzy I’m not sure about them never being water based, as old msds shows soluble content in the formula but regardless when you give anything enough time to cure & do light coats you’ll be ok. I would highly recommend switching to a solvent based filler primer like upol. I’m doing another video like this with some new primers.
Where is Part 2? I subscribed but cannot find it.
It’s being edited, it’ll be up soon!
Well done as always.
Thank you!!
Is there a part 2?
Should be up in a week
What do you think about uv resin as a filler? Is it comparable?
Not a fan, it’s toxic, if not fully cured it will affect top coats, you have less control, you’re fighting gravity & it’s very easy to lose definition in detailed parts of the model. I tried it & personally it didn’t save anytime just was messy and more of a hack than anything….but that’s another video.
@@Darkwingdad thanks!
Part 2 still in the works?
Weather has been terrible, most is edited just 1 test left
Where is part 2?
Being edited this week
