About $50 for the el-cheapo bench machine, each wheel is about $5-7 one per compound you can mix them up, compounds are about 5$ each you need black(heavy cut), red(med cut), grey(light cut) atleast. Greasless is $8 a lb, you need 5 different grits 80, 120, 180, 240 & 400. then you can hit black rouge on up. Each little felt bob is like 3-7$ each for the roto tool. BTW the shaft is 1/4" so a dremel wont hold it.
so at min, around $100 for wheels, the min needs compounds and a few bobs. Plus a can of brakecleaner to get the black shit off between steps, a wheel rake $15 to clean/scuff the wheel between compound applications, some wetsand paper you will need here and there, then you want some zoop or what ever aluminum sealer to keep the shine.
Thanks for the props! +1, 4 u!
Yeah PM me if you want, I can do it for you for less than the cost of materials I quoted above.
