Painting over powder coating

Post by diamondback0320 »

Anyone know if this can be done..if so what's the prep.. have a fuel tank out of the boat to clean out & freshen it up but it's going to be about $100-150 just to blast it

All you need to do is just sand it or scuff it up so the powder coat and it would not hurt to use a good primer that will help adhesion then put a good quality top coat paint on it, I have been painting most of my life and painting over powder coat is no big deal as long as you prep it right

I kinda figured a good scuff & wipe down with acetone & good primer was the route to take as I was a painter 20+ years just hadn't ever dealt with this situation thanks

Powder coat is one of the hardest coatings to adhere to. You can abrade it and get a bonding primer as a tie coat to create a mechanical bond. It will work.... kinda. When you bang it, it will still pop at the primer 90% of the time.

Stripping it is the best way.

Also, if the powder coat is chipped, you will have to sand All the way down there or you will see a ridge due to the high millage that powder typically goes on... not that much more effort or money to strip it and start with bare metal.

Both work. One way just works better. More of a personal decision than a right or wrong kind of thing.

I have purchased it before from Advance Auto Parts in the paint and body section. Seen spray cans and quarts.

It helps to have scrapers and requires a little bit of timing FYI. You apply it and it starts to soften and lift a finish. As it dries it sort of retacks so you need to hit it just at the right time to get a clean scrape. Then clean the scraper blade and hit your next run. That's my experience anyway on a painted surface.

Well I tried it yesterday afternoon..sanded with 80grit then rinsed it off & dried it..then sprayed the tank & let it sit bout 10-15min & went to scraping & let's just say it didn't do as desired..I used a whole can on the fuel tank..now I've really got a mess.. maybe do to temps being too cool as it was 67 when I sprayed it.. guess I'll just put the tank in the sun for a while and try again & hope for the best
