I recently purchased a kit from GB, from what I could see it was in great shape. Well as I own a cerakote business I started blasting parts. Come to find out it appears the seller coated all the parts with sandable filler primer and then rattle can sprayed black. Now the top cover, rear cover, bottom cover look like they were on the ocean floor. Nothing that would compromise safety, however cerakote is out of the question. What should I do, replace the parts with parts that have better finish or try to sand down the pitting and try some type of high temp paint?
