Saw a very strange problem tonight and I am wondering if any of you have seens something like this before or know what it is.
So the client has a 2000 Honda Insight. This car has an aluminium body. He left some boxes on the roof of the car along with a garbage bag for about 3 hours. During that time it rained and it was a very hot day.
Now the area where the boxes and bags were are discolored. Instead of the deep red, it looks white. The client tried various things to fix it without sucees then called me.
First thing I tried was a mineral remover. I did not believe it would do anything but wanted to make sure it wasn't some form of water spot type problem. Did nothing to it.
I then clayed the areas. Again, nothing.
Went to a compound (D300 with cutting foam disk on a PC). Didn't do anything.
Paint was rather thin (105-115 microns on the roof, 77 microns in the door jambs). I did a very short wet sanding using 3000 grit 6 inch disk on the PC for 2 passes at speed 4. Compounded again, still no change. Mesured the paint again: 95-105 microns. So I suggested to the client we leave it there. Nothing seems to work and paint is very thin. So I polished the roof and stopped. I wanted to apply a sealant but I suggested against it in case it's some humidity stuck in the clear coat from the car being boiling hot, then rained on, My idea is that some water might have gotten in the pores of the clearcoat while it was super hot and trapped it when it cooled down. If that is the case, I told him it might fix itself then next time the car gets super hot. But honestly, that is a wild guess and I really don't know what the issue could be.
Help me Obi-Wan Kenobi, you're my only hope!
