can media blasting fix sand blasting grainyness?

[KyleCrish]

i had a set of mesh wheels made of forged aluminum sandblasted because they guys who did it said it wouldnt make them too rough. well, its too rough to paint. and i dont have the time to prime, sand, prime, sand. untill they are all smoothed out.

so, is there any media that can smooth these wheels out to the point where they can be primed and painted? i dont have any experience with this so i need as much help as possible.

these are the wheels, so you can see why i dont want to get sanding.

Sandblasting is like sanding the rough sand will pit the rims the smother the better. Find out the coarseness of the sand they used on you rims. Maybe you should take the rims to the pros who refinish rims for a living and see what they could do.

I brought them to a powder coater today. He used aluminum oxide i think to smooth them out

Bead blasting would have been the option you wanted. It leaves a nice finish on the parts.

Just have them powder coated. Or at least primer powder coated then scuff the powder and paint on top

The fact that no one doesn't read the comments others left makes me wonder. This question has been answered and the wheels are already done.

Please have this discussion closed.

vdub@toronto was it even necessary to reply? I am sure that if they are real rough that just blasting with alum oxide will not make them smooth enough to paint. Like I said your best bet would be to have the primed with powder and then paint over that

[KyleCrish]

sorry i havent replied guys. for some reason these comments didnt show up in my subscribed threads page. the wheels were finished and painted. i dont know what he ended up using, but it smoothed them out pretty good. not exactly what i wanted. but good enough to paint and not notice.

Wow people can't read (****). The rims are already done

[tomespo]

No ****!! I read that. However he just had them blasted with alum oxide you idiot and I was trying to explain the right/best way to go about doing what he wants to do. But hey I just have 84 wheels sitting in my shop for no reason

i hate you Tom

remember, that 1 person always knows everything, no use trying to explain it to them because they already know
