How do you correctly remove oem powder coat from rear shock spring(s)? Using heat, burning it off would re-temper the spring steel, so that's a no go. Glass beading w/ aluminum oxide would take 18 and a half days. I'm clueless on how to correctly get it off, and also in a feasible manner? TY
I just googled it, Chemical strippers. If any mods read this, please delete my post. I should have googled first. Sorry.
Chem, How dangerous is it to work with? Rubber gloves & goggles for sure, but do i need a respirator? Thank you
Gloves for sure. You usually cant get pure NMP...it'll be mixed with other solvents. But anything good will have NMP in it. If you want to do it fast warm it...carefully. We use it crock pots or deep fryers (fry daddy is common) on low due to flammability. NMP will eat/remove/soften cured epoxy, urethane, etc. If you have a place with ventilation thats fine.
Isn’t powder coat basically PVC, so acetone should soften it so it can be wiped off? Hrmm… do I have any shock springs I don’t care about downstairs…
I used a really good product a couple of years ago, made specially for the job. I can't remember what it's called but if you can hang on for a week to ten days I can look at the bottle when I get back home late next week. The stuff was easy and safe to use.
Found it after a little search. https://www.removepowdercoatpaint.com/product-page/1-gallon-remove-9000-dissolver
I got plenty of time.... just getting my ducks in a row for an upcoming project. Thank you! Thank you everyone else too!
What are you talking about? Blasting it off would take maybe 30 minutes. Drop it off at a local blasting / finishing shop and it'll be done for $25-$50 and ready to repaint / coat.
The guy that blasts and primes my stuff recommends burning powder coating off with a rosebud prior to taking it to him. Powder coat sucks. Quality paint is superior in every way.
One of the problems with powder coat, I've been told, is that if the metal underneath gets damaged, ie. cracks in the case of a frame, it completely masks it, where the crack will show up if it's painted.
Yes. A good strong, tough powder coat CAN hide small defects or cracks that might show through liquid applied paint. But powder coat isnt magic. Its a binder and pigment, just like liquid paint, only its solid at room temp. So you have to melt it so it flows into a film and turns into a coating. Whereas liquid applied paint is sold but its dissolved in solvent and applied. When the solvent evaporates, you get a solid film coating.
