Hello dear people, a friend of ours has next weekend’s birthday and what does it have to be? Sure, a rear spoiler for the wall. Said, done, we were able to find an old Supra Spoiler in the Netherlands yesterday. Now the paint from the part is relatively over and we would like to repaint it. What do I have to consider? What do I have to grind with? Must I prime? Rich desired color + clear varnish? What kind of paint do you use? or is it worth the way to the car dealership? Look forward to your answers! Greeting Felix
