So Ulf, You are stripping paint. My 65 was restored earlier by someone else, and they coated the bottom, engine well, under the hood, and inside the truck with that black undercoating. I used Air Craft Stripper to remove it, so I know what you are going through. Hang in there as it will get done......and done well I am certain. Any color picked for the car as of yet? Best to you. sgrip65
