I posted the problem I had in WIP I did for my 1/18 Willys gasser. I let it dry for more than 48 hours. I had to turn it upside down to work a couple of chassis bits. I set it on a new micro fiber towel. Had it that way for about 15 min. When I turned it over I saw that the towel had imprinted into the clear. Had to sand the roof and repaint and clear.
