tips on painting grill

just painted my grill black did everything i thought i was supposed to, sanded it primer then paint, this was about a week ago....just noticed the paint flaking off

 

Use plasti-dip next time mon.

 

noooo plasti-dip = fail
its cool for a while but it just comes off after rubbing on it and you have to worry about being careful with it. do it right. just re-sand, re-primer and everything. what paint did you use?

 

Here's what I used and these are things that were recommended from a paint shop so its not really available all around but they said these 3 things are the best to use. Middle can is the color matched spray so you can ignore that but the other 2 are important. Did you clear it as well because thats really what keeps it from chipping.

 

gotta sand the primer before you spray it. Plus, rattle-can paints DO NOT have the adhesion that pro-grade paint does, so yeah, chipping is gonna happen.

Sand it all down again with some 600 grit paper. Don't sand through the primer, just scuff the primer, and sand the black down all the way. Then re-spray. It'll last longer this way, but at the end of the day, it's rattle-can paint. You get what you pay for.

 

Did you use any adhesion promoter? I think that might also have something to do with it chipping off.

 

nope

 

I'm not sure if that's why it's chipping but that might be why.

 

I haven't painted my grille yet, but I did a dodge grille and some side steps, usually I sand blast them to remove the chrome and pit the grille then use adhesion promoter/primer and some good acrylic enamel paint and they're good to go!

 

Surface contamination will also result in the paint flaking/peeling.

Before you sand, clean the part, when dry wipe down with paper towels soaked with denatured alcohol and allow to dry. Do the prep sanding. If you don't clean the part prior to sanding, any dirt/contaminants on the surface will be sanded into the surface of the part and the paint job will have flaws. Clean again with the denatured alcohol. DO NOT touch the area that is getting painted with any part of your body. Body oils will contaminate the surface and the paint job will fail. Prime, lightly sand the primer, and guess what..... clean it again with the denatured alcohol. Apply the color coat and clear.

Cleaning the surface prior to applying paint is just as important as any other step, and it's a step that many people forget about.

 

I got tired of my black paint chipping off so I said fuck it and just used a rhino liner type of paint, it worked out pretty good for me.
