as usual sswee is right on the money. an ir thermo is a must. also i would add a few cautions i have learned the hard way. pre powder prep solvent varies with user, but what works for me is brakeclean aerosol or laquer thinner. i also have used mek but it is nasty stuff so if you go that way be sure to use ALL the safety precautions listed. also you will need a dust mask at the bare mininum, preferably a respirator. though not super harmful to the health powder is not good to breath, and wear the respirator when blasting. stay away from sand in the sand blast cabinet. also if you plan to do any of the high temp powder ALWAYS remember to keep it away from any other non high temp powder and clean the pc gun spotless when changing back to regular powder. the high temp is silicone based and if mixed with regular powder, even the smallest amount you might as well throw the regular powder in the trash as it is ruined. also if the parts are used, the fastest way to strip paint is aircraft stripper,not the low odor kind, available at most auto parts stores. be careful with this stuff also as it can burn the skin. one last thing when doing cast parts, especially aluminum, they need to be outgassed. if you dont know of this do a search on this forum as there are quite a few threads that talk about it.
best of luck and welcome to the world of powder, get ready to be an addict, as sswee said you will want to powder any and everthing
