How does everyone do it ?

JHFGSX9D,

Try running your bob over some 80 grit sandpaper, that should loosen it up so that it will hold the greesless!

That makes perfect sense that would explain why the **** doesnt stay on the bob. This would allow the greaseless to hang onto the bob !!

Thanks for everyones help !!

I started to sand my compressor housing for the PT71GTS and it is pain in the butt. Looks like I need to get some greaseless and felt bobs. If you use greaseless do you still need to sand it down? Thanks.

the greaseless will take place of the sanding to 400 grit. above that you will still need to sand with paper or wheel with a spiral or vented and emory.

turbohardtop,

I just finished polishing a T3 Compressor housing and had to go all the way to 1000 grit wet and dry. I wet sanded it and, then used a Sisal wheel with Emery.

the sand cast process on the compressor housing make it so rough. I tired it sand it down by hand with 160 grit but I gave up since it was going so slow. What tool do you start with? Should i pick up a die grinder? I do have a dremel with a flexshaft on it. Thanks.

for real rough castings i recommend a die grinder with flap wheel first to knock down the real rough stuff then with the same tool move to bobs and greaseless. always work from the tightest spot to the open area. i do this so i dont get discouraged when the tights take a while. best of luck bro and keep us posted on the progress.

I am about to pick up an air die grinder. Is 90 degree angle die grinder necessary? or do you guys like the straight die grinder better? I hope to get some pieces polish so I can post picture of my engine bay. I am prettying up an 830rwhp car. Thanks.
