Russ, I had a body guy do it. So i don't know to much details. He was concern it was a leather material and that he would have to cut it out. I told him it's fiberglass so he can sand it down. He knew exactly what to do after that.
When i had my 328 roof colour coded. The painter used a DA sander to take of the texture and smooth it down. Its a simple job for a good body man. Ya roof looks good by the way Chris.
