I have never polished anything before and i saw a guy polish his intake maifold, and the lettering on his valve cover... he said he used a soft grinding wheel and then sanded it 400 1000 2000 grit sand paper, well sounds easy enough but i was just wondering if anyone has any techniques (sp?) that would help me out... i have a few extra parts laying around and wanted to learn this, thanks, also i hear about people porting their intake manifols and tb's and i wanted to know if anyone had a write-up or and hints or techniques on how to do that, thanks alot
