Paint help

Post by 1slow64 » Mon Aug 05, 2013 6:32 pm

Alright I need some help with what the heck is going on here. I've tried painting my bumper 4 times now, 2 times the base cracked and now 2 times the base has turned orange.

I understand that I most likely was spraying too much base when it cracked, but why in the heck is it turning orange?

I've prepped it, used a high build primer, then a black sandable primer. Finally sanded it smooth with 500 grit and cleaned it off.

Base is PPG Shopline Plus, which is the same thing that was used to paint my old 67. I make sure to shake it up really good and stir it up before spraying.

I was hoping to have it ready for Ardmore, but it's not looking like I will be done.

Its hard to see this time as I only put 1 coat of clear on it.

This is a better picture of what is happening.

I originally thought it was the clear the first time this happened, but when I tried wet sanding it didn't do away until I was back to primer.

Alright, just got off the phone with Troy, going to try what he recommended and see if that works. Will try and give an update tomorrow as long as it doesn't rain.

Cracking on bumpers, I avoid the high build primers because they tend to be thick and a little more brittle. They do not flex like the urethane bumper wants to.

Color bleed like you are seeing, either you are not using a quality sealer between your sanding work and the paint or maybe you are rushing and not letting the sealer have the correct flash time.

If where you are right now is a smooth finish of clear coat and discolored, let it dry for a day, lightly sand the clear and throw on 2 more coats of color then clear. The clear on it now will act as a sealer and should hold the color mis-match sealed in.

that almost looks like there is a solvent or something in that area. so did this appear in the base coat? or when the clear was applied?

Well it looks like Troy's tip did the job. Raining now so I can't put the clear on.

Flat black spray paint prior to applying the base coat.
