i sand it completely smooth up to 360 grit. i only use white buffing compound on the buffing wheel and it polishes it well.
this corner and on the top of the intake is where im having problems
i think it may just be the aluminum, i tried the dremel on a waterpump cover and it seemed to work well.... and i noticed it takes a little longer to buff the flat sides with the buffer than it does other aluminum parts stuff ive done...most things i do will shine within a couple seconds, but this takes longer.... even if i try red rouge.
any ideas what to do?
