when I powdercoated mine on my 1g I sand blasted it washed it with simple green and a pressure washer to clean it up before the coating process. it then got pre-cooked to get any oil out of the metal and help prevent outgassing. it then got washed again, then dried in the oven for like 10 mins before it was coated. I never pulled my baffle off, so i don't know if there was any sand left over, but it has been on the car for 6 yrs without a motor problem. to my knowledge, ANY of the vc's I coated (100's) have never had a problem with sand damaging the engine. just depends on who preps it and their process I guess.
