I was talking to a paint guy at a car show a few days ago. He claims that the way to do this is to HEAT the part first, and then spray the paint on it while it's hot. uzzled: This way the paint will "bite" into the chome as it contracts when it cools. He claims the factory did it this way.....I thought they did it electro-statically. Any opinions on this?
I think the guy is a hoser. Chrome plating just needs to be cleaned, have it's surface area increased (scuffing), cleaned again and have a good two-part epoxy primer put down first to provide an excellent base for further primer/sealer/topcoats. Applying color to a heated part may adversely affect paint flow, cure time and in the end may even show a slightly different shade than what's applied to an ambient temp part. Devon
What he actually said was the PRIMER is applied to the heated part first. Then the topcoat is applied with the part cooled........I probably should have said that in my original post. ou:
I've always used PPG's DP-40 epoxy primer over prepped chrome at ambient (and even colder than recommended) temps. So far in 20 years or so I've not seen an issue...just my $0.02. Obviously if the chrome has poor adhesion any topcoating will suffer accordingly. Devon
