Re: need help
What kind've part is it? Does it have a rough cast finish? If so, starting off with buffing is skipping a step. It will need to have the roughness sanded out first. Get down to at least a 400 grit, (600 would be better), and THEN start in with the emery and buffing wheel.Originally posted by UFpball7
Some pics of the part might help us help you better. Depending on how rough the surface is to start out with, you may not need to go as low in the grit range with sanding. (Which will save you time and energy.)"Some people are like sandpaper: they may delight in the misery they inflict by rubbing up against you, but in the end you will come out smooth and polished while they'll just be ugly, wrinkled, and used up." - Beyonce Knowles -
Re: need help
pics would be a big help in deciphering the issue you may have. it is possible that with the dremel tool and the small attachments you are using that if you stay in one spot to long it will cause the ripples but at this point that is just speculation.Originally posted by thesoundwhen in doubt polish it out/ why replace it when you can refinish it
