Can waxing red cars turn them pink when left in the sun

You are correct that I don't have a clearcoat; it's a 1972. when I wax the car, I always get paint on the rag. Wax IS slightly abrasive (I use a carnuba wax). If i were to wax it too often, it would eventually thin the paint and thus cause blooming. I don't use a liquid polish; I can see how my post suggested I did. I put the word "a" in by mistakle! I keep the car clean with a dry soft cloth every couple days to keep dust from accumulating.

Carnauba based waxes tend to evaporate, lasting only 4 to 8 weeks. When applied correctly the coat is so thin that no crazing should be visible. Sounds like something else is going on. I use S100 (aka P21S) on my '87 (which has no clear coat) and have never lifted any paint. The only time I've lifted paint is when using a polish.

 

If you're lifting paint with your wax then you should change your wax (unless you want a polish/wax in one). A pure wax should not have any abrasive characteristics about it. There are a lot of threads around and as many opinions on which ones to use. After a lot of research, and until I go to a synthetic sealer, I chose S100 which can be purchased at your local Harley dealer. It goes on very easy and doesn't haze or leave any white residue (it's clear).
