Beautiful video! Finally a video that answers a simple question with a concise 2 minute video.
I hate 2 minute videos dragged out to 10 minutes because the guy loves to hear himself talk and ramble on about nonsense and then repeats the answer 4 times. "So, like I said..."
I have watched a lot of these videos now, and consider them my go to for information. There's a lot of conflicting information out there, so it's great to see someone who really specializes specifically in painting.
you are Right Brad I have gotten away with wet sanding guitars a lot of times. but i did a Jackson Explorer the paint game out so nice I was impressed .wet sanded it and the next day it swelled badly at the string through holes.
Damn, that must have been frustrating. Wet sanding is nice, but just not worth the risk on wood in my opinion.
i did 2 guitars with water based acrylic topped off with gloss poly. On the first guitar i didn't wet sand at all. On the second one which is a jungle camouflage style, i used 3 coats of clear and i wet sanded the second coat of clear just so i could remove orange peel/drips from the first two coats and so that the final coat of clear would look like glass. It turned out so good i didn't even need to polish it with compound afterwards. But yea i agree don't wet sand bare wood or the paint before its been protected with your clear coat. Cheers from Ontario Brad, Still tuning in \m/ Go Coors Light!! cheers \m/ ps. i should also say i completely hand painted with brushes for the paint jobs and used foam brushes to apply the poly
That's great Mel. I've glad that your projects turned out well. When I'm applying a finish by hand I often sand between coats to get rid of any brush marks etc.
What no load grit paper do you use?
Maybe I shouldn't have, but I pretty much skipped sanding. I lightly went over some rough spots, but I left anything that was smooth well enough alone. Then added polish. Guitar still came out looking like glass. Smooth too.
If a spot is perfectly smooth there's no need to sand and polish it. Generally we just do the whole surface in order to ensure that it's nice and flat.
Brad whats your workout routine haha just kidding!
seriously though...
Do you have a preference when to switch from circular pattern to straight line sanding? I tend to go in straight lines from 400 grit upwards but curious on what you think. Ta
I generally sand wood in a straight line with the grain. For sanding paint or a finished surface I just try to keep it even. I don't concern myself with direction.
When you change direction from one grit to another you can see if there are still scratches from the previews grit (only on the paintjob, not on the wood)
Kinda like when you clean a windshield from the inside and outside.
(you'll know on which side the smudges are)
I have a question about grit and how that relates to whether you're wet sanding or dry sanding. I'm not sure where I heard or read it, but someone stated that you need a higher grit if your wet sanding than if dry sanding. Is that true, or is that nonsense?
That’s nonsense, but it’s probably a misunderstanding of some general principles. People generally will wet sand with higher grits, whereas with the heavier grits there’s often no point.
What do you mean by no load paper? Is there a particular brand you prefer?
Basically the wet/dry paper. I like 3M, Norton, and Mirka, but really there are lots of good brands I’m sure.
Thank you. I actually came across a company I am sure you have heard of. If not you should definitely check them out. Eagle abrasives/Kovac. They make sanding paper specially for dry sanding. It works great. Thank you for your reply.
Cheeeers
I miss those 2 minute videos rather than 12 minutes nowadays.
do you ever flowcoat your projects or always polish afterwards?
I almost always polish. I only flowcoat on small, less important projects. I don't find it as reliable personally.
+Brad Angove you have a point there is no guarantee you wont get dust on your flowcoat
Very true.
