I'm getting stuff set up so I can paint my '51 Chevy this spring, I have just a small amount of block sanding to finish up, b4 I DA the area's that did not get any filler. do I have to remove all the stainless trim or can I leave it to paint? also, what temp to paint in? I have a portable tent type garage that gets pretty hot out in the sun, this is where I'm going to do the painting but how hot is to hot or too cold? on a 65* day it might be 75* in there, of course I will circulate air within the garage with a fan, and wet the ground or use plastic sheeting under the car and wet that.
