How to repair HT Autos Bodykit?
 

I just recently bought an HT Autos Bodykit for the 2016 FRS. It's made out of polyurethane and I saw that if you looked close enough there were small micro sized craters, some large, scattered all around. I'm guessing this is from the manufacturing process?

I went to the best auto body shop in my city and the tech said they were uncomfortable trying to repair the body kit because even if you tried to put filler in, when the paint gets applied, he said it would get sucked back into the pocket of holes. He mentioned that there were some shops that specialized in repairing aftermarket parts, but I had never heard of them before. I don't even know where to look.

What would do you in this situation?
