Is sandblasting required for powdercoating?

To ensure proper paint adhesion, the part needs to be completely bare to the metal. To be certain of this, yes, sandblasting is the best way.
In power coating (and you can do a Google search to see this), a charge is put into the part with an electrical current. While charged, dry powder paint is sprayed onto the part. Since the part is charged, the paint adheres to the metal in a clean, uniform manner. The whole thing is then put into an oven to bake the paint on.

thanks for the process... i guess what i need to know is if the part (wheels) is NOT sandblasted/stripped before it's powdercoated... what are the advserse effects?
will it still be better than painting?
will it start to chip soon?

I suppose you could try. I find with such things, that if you put in just a little effort, the results will end up being disappointing. If you prep the rims really well and spray painted them, they'll probably last OK for a couple of years. After that, they will likely begin to chip and peel.

Your rims probably won't be sandblasted. Most likely they'll be bead blasted using plastic beads (maybe glass depending on the finish and metal you are trying to strip). Plastic beads will strip paint without damaging any of the surface metal.
Do NOT skimp on that process. As they say in the detailing business, the results are all in the prep work. As xviper says, most shops won't guarantee the finish until they can strip it to the bare metal.

I kinda doubt any powder coating shop will do the job unless the part is properly sandblasted. At least they won't guarantee the work.
You could try to just sand it really well and see what the shop says.
BTW, most powder coating shops will do the sandblasting for you.

if i choose the NON-sandblasted route... will that still be better than regular "wet" painting?
im NOT going for showroom quality... only need it to last 2-3 years... but will see time on hot road-course enviornments...
