red paint...

[PetesPonies]

I remember first seeing this problem when I was a kid . The problem is the "purplish" marks that show up on red acrylic enamel paint many times. It happens once the paint is older and looks strange.I'm pretty sure it is a pigment problem, but never knew exactly why it happens. I can't tell you how many times I have seen this, but alot. What promts this question is I got a car in today to work on, and it has them. Solve my question here somebody :o)

I have never thought about why it happens, but it is more of a "stain" than anything. It is a LACK of red pigment there, probably "bleached" out by something. I believe I have seen that very thing happening when getting exposed to acid from the battery.

I'm a "red" freak. I've probably owned 70-75 cars and the vast majority have been red, so I know of the purplish thing of which you speak. To me, it was most noticeable on vehicles of the mid-80s years. I have no idea what causes it...it just is. I've never seen it on aftermarket paint, only factory paint.

I haven't noticed it since the early 90s models. I have a bright red 92 Camaro that I bought new. About three months ago, I refinished the front and rear bumper covers and got an excellent match out of the can with no tinting or blending.

and funny enough, I see it a lot more on repaints, not factory :rolleyes: I first noticed it as a 15 year old on my red '57 T-Bird...I wasn't happy:( It also appears to be on areas where the sun gets to it more; top surfaces. I haven't ever seen it down on a side panel.

Like I said, a "lack of pigment", red pigments are the first to deteriorate.
