Got some GT88 scratch remover ("from the makers of Didi 7, as seen on TV") about a year ago to fix a few scratches on the wife's black Caravan. Didn't work so good for really deep scratches but I kept the stuff around. I had two 1/2" long scratches on the hood.....the kind made when a small rock does a "skip" along the surface of the paint. I cleaned them off and could feel the rough edge with my fingers and they were quite visible. Also had a regular rock chip that hit just on the edge of the 3M film. I was about to go at it with touch up paint when I thought, "What the heck." After I wiped these places clean, I could NOT see or feel the scratches anymore. The rock chip I could still feel but I could not visually detect where it was. Who'da thought?

 

How does that stuff match your color?

 

It's not a color match product. Not sure how it works. It seems to fill the scratch smooth out the rough edges and optically blends the scratch away.
Worked for me.

 

xviper:

I've got four small stone chips on the hood where the clear coat finish has been broken, but the paint has been left intact. I've noticed that when I apply Zaino to the hood, these chips become very noticeable - even after polishing the wax off. However, I've also found that if I rub the chips with a cotton swab and alcohol, they become invisible again. I used an eye loop (magnifying glass) to verify that the wax had built up inside the break in the clear coat, causing a contrast between the paint color and the wax. (Being a white car, this is probably more obvious.)

My guess is that the GT88 works by smoothing out the edges of clear coat to prevent any wax or dirt from building up inside the break in the clear coat, or at least, makes it easier to remove when polishing.
