Next set yourself up with a nice work bench with alot of space. As you work on a piece the buffing wheels and the compound will fly and make a mess. I attached the 6" 1/2hp polisher to a 2X12 and extended it off the edge of the bench so you can work a piece without hitting the bench top.
The greasless stuff here will almost completely eliminate hand sanding a piece. You basicly apply the stuff to a buffing wheel and use a hair drier to dry the compound. Once it is dried, in about 5 minutes with a hair drier it is rock hard and creates a cutting surface.
The greasless goes from 80, 120, 180, 240, 320 & 400 grit. 400 grit you can start with a Black rouge, but i would still wetsand with 600, 800 then even 1000, then hit it with black or brown/red rouge.
Other tools that will help you out:
Roto tool with a 1/4" collet, and a flex shaft. This is used for the buff bobs and sanding cartidges.
Air compressor, to power your die-grinders and DA sander. Also a air nozzel to shoot off dust and crud from your parts.
Brake Cleaner… blasts away the compound and black redisue.
Wet Dry sand paper: 120-1000 grits
PB blast or WD-40: I like this instead of just water for wet sanding, it helps keep the metal from sticking to the work and the paper alot better than just water.
Here is the 1.8t intake manifold I finished up. It was rough cast aluminum to start and the 80 grit greasless cut the cast down like butter, it was unreal how fast it flattened out the surface.
Again, ill come back when i have somemore time and add alot more detail to this. And spell check it! lol
ATP 3" Stainless Vband big turbo downpipe. Figure why not, it will be right on top so you will see the first part of the bend. Used 400 Grit greasless, then black, brown, grey rouges and good old mothers mag polish last.
The stainless… I am not sure to tell you the truth. I know the heat will blue it, but aslong as you dont let water, coolant or shit like that burn into it it will stay nice looking. All the titanium and stainless pipes I ran on my bikes are allways nice looking, until i let dirt/mud burn into and stay on them.
LOL, saturday is going to be balls hot out… so I plan on working in the garage and doing some airbrushing and shit in the cool basement… if you wanted to ride down we can polish up your shit.
