Hello
I have a 1985 Porsche 928 that I purchased used and needed a detail job. It is a repaint, single stage black. I rotary polished it with Optimum Hyper Compound, orbital with Optimum Polish, followed by Meguiers #7 and Deep Crystal carnauba. Looked amazing after I finished it, but once the surface got hot, the reflections went all blotchy. I stripped it again with an orbital and just used the Deep Crystal, thinking the #7 was causing the problem. WRONG same thing happened again. When the surface is hot I can smudge the surface with my finger and leave a mark with my fingernail.
Ist pic was when it was first finished, other 2 are reflections after it was heated up.
