It1S10 has it right.

I did my BB Chevy intake and water pump. Each, especially the intake, has lots of tiny, hard to get to corners and angles etc. It kicked my butt. A rear end housing would be relatively easy.

My polish job ain't exactly show quality either (see kitz in gallery). But it looks good from a few feet. In the end I got it as far as my patience would allow. At least 40 hrs in the both of them.

Then I clear coated it with clear engine paint. That dulled it ever so slightly but I think it will hold up for a longer time.

Next time I will buy my stuff already polished.

Good Luck! Kitz
