@@thehighwayman78 no, filler always goes directly on metal. Ideally you don't even want any of the old finish under your filler.

As a professional accident repair and paint technician I must say you did a very good job! Most people that are not in the trade do a terrible job. Well done 😊🎉
Hi bud your totally right, If I got filler wet I would in most cases re do the whole filler job as its not worth the risk of bubbling the paint in the future but It's hopefully degreaser in that bottle? at least it's what I'd use :) For what seems like someone not in the trade I am pretty impressed with OP for the most part :)
Hi, I don't think so otherwise how did he grind it all down from the outside without going through the other side leaving a hole or more rust? Didn't look like it to me, but even so I was only commenting on the little bit that I could see in the short clip 😅
So when 'top coat' is added, is that basecoat (paint) or clearcoat? Because it looks like it is paint and that no clearcoat is added in the video. Was great up to that point! 😉
Mercedes, MOPAR, NISSAN took off the Zink plating that was introduced in the 80s to prevent this horror. I fixed many GMs ,Jeeps in the early 80s with rust spots like this on new cars with 6 miles from dealerships. The body fillers needed to be changed to adhere to this plating. Ok back were we started from!!!
You should have ground the rust out completely before putting the phosphoric acid on it. Sanding the metal afterwards removes the protection that the acid provides. It's a chemical reaction with the steel to prevent further rust. It's not just a "rust converter."
You either have a van in primer colors, or - if the 'top coat' (aka final thing to add, because it is the... top. coat.) is the desired color - you don't add a clear coat..? I thought all cars have a clear coat on top of the paint. As for the rust: nicely done. (Though i don't understand the extra step of rust removal after the rust removal; very thorough... and most likely a fix that will not have the issue return suddenly. Well done)
You should look into POR15 if you have places that are prone to rusting. It treats metal so it won't rust again, and also stops spreading of rust. A little pricey, but worth it
So convert the rust to feric phosphate and then remove the ferric phosphate. Seems legit. Why wouldn't you just remove the rust like you do in the end anyway? Must be a generational thing. 🤷♀️
not bad, I would you a spot blasting gun to get all the rust out and use an etch primer first as standard primer doesn't really adhere to bare metal or filler
1 Remove rust with sandblast 2 aply epoxy sealer 3 use putty/bondo 4 close it with primer 5 than paint Other way, rust will come back quite soon. I have 27 y.o. BMW. I know what I'm taling about.
Im not sure if this is the right way ,why put on the rustconverter and then grind it away. I think i would grind away the rust first ,then aply the rust converter and then the bondo
Ypu should not wet sand body filler that is only for primer and painted surfaces. Body filler is very porous and will absorb that water and not release it for hours on hours (way longer than you waited to coat) resulting in the moisture getting trapped and slowly rotting away the steel and in this case there was previous rust exposure making it easier and quicker for that moisture to take hold and corrode the metal away again leaving you where you started but worse off
@@ltmltm4945 I would sand it with a Dremel after using the rust converter, because most rust converters barely do anything, so sanding down to bare metal would be better, and actually you can probably just skip the rust converter part, sand to bare metal ensuring no rust is left, use a body filler to fill in the sanding spot, sand flat with a lighter grit, primer, paint, and clear coat, and then you are done.
@@ltmltm4945 After I clean everything with wire brush, flap discs, dremmel and everything else 🤣 I put phosphoric acid just after I cleaned everything to a healthy bare metal.. Then remove when residues comes up with steel wool and after that give it a wipe with alcohol, after that put again phosphoric acid and dry it clean with industrial dryer and paint directly after drying because if you wait for a day it will start flash rust again.. If you don't use phosphoric acid and you paint over healthy bare metal, be sure that a little rust will be under paint after few days no matter you are sure there was no rust until you painted, it starts to rust instantly if there is humid air and 1 dot of rust left is enough for the cancer to spread under the paint, I tested it on my w124 with all combinations.. I skipped some steps but all the crucial steps are written, good luck guys..

Don't fill holes weld new bits in. Rust treat after grinding .

Flap Wheel enters the chat!💪🤙
Use "soft-edge" masking tape it has foam inside it to help the paint feather at the edge so it won't require excessive sanding
All of this is good advice But the rust will return usually within 12 to 18 months so be aware, and not too heart-broken when it starts to bubble back

What "top coat" are you using exactly? Most rattle can spray paints will not polish to a shine after wet sanding.

If i was gonna go throughball that i'd probably do a vinyl wrap and add an extra layer to protect it from the elements.

Hello how do you paint match the exact color? Is there a number I need?
Your car has a color code number
Do you use clear coat?

Oh man, do you think rust working just outside? a couple of month later rust coming back again
Sprinters have serious rust issues in the rust belt.. but I'll bet there isn't one spot of rust underneath?
why treat it if you're just grinding it out?
Don't wet the polymer before put coat on it because it's make bubbles after paint and little time
Don't wet sand filler. The talc powder in it will suck up moisture and trap it against the metal
These spots always start on a Sprinter or Transit after a couple years of use.
Why apply rust preventer, and then sand it off ?
Maybe to spot all the rusted spots? Not sure. I was told to never sand after you use a converter.
