My friend who paints cars is going to paint my front bumper (89TA) and my new Gfx's sides and rear bumper (91TA). How much paint should I buy and also what is that orange stuff that I am suppose to put in the paint with it, i think its orange.

 

are you talking about flex agent? never painted, so i don't know what color it is, but you have to put that on flexible pieces like the bumpers

 

You can buy paint with the flex agent already in it.

 

if your friend paints cars, you should go ahead and ask him every brand of paint is different... but I would think it is the flex agent... as for the amount of paint, it depends on the type (base/clear, urethane, enamel) and the color.. and the way your guy applies the paint
