There's your problem, unless you are doing a steel frame there is no way they should be bead blasting it anyways. Chem strip is the only way to strip aluminum.istomtom said:I wasn't too impressed with az powdercoat. Lots of blasting media left rolling around in the frame. Minor imperfections. I had to spend a good 30 minutes with an air compressor getting all the blasting media out of the frame, especially the chain stays which would have ended up in the bottom bracket eventually causing premature wear.
I have switched over to vyne powdercoating in Mesa just across the 101 on Broadway, google em. Ralph is the owner, great guy, knowledgeable and their stock color options blow az powdercoat out of the water! He can also turn stuff around MUCH quicker than az powdercoat which has a minimum 7-8 day turnaround right now. vyne powdercoat media blasts on-site, apc does not (and they won't take responsibility for damage caused by 3rd party strippers).
