It has some dark stains due to age and yellowing because of previous fuel leaks.<BR>
Is media blasting a good solution?<BR>
What type of media?<BR>
Should it be clear coated or treated in any way afterwards to make the fresh appearance last longer? Thanks!<BR>

>>>I would presume a ZF case and an intake manifold would both respond the same. When I was at Lloyd Butfoy's shop helping to rebuild my spare ZF, he had be blast the cases with a light abrasive compound (it wasn't sand, it was a slightly abrasive media, maybe walnut shells?). He sprayed the whole thing down with a very liberal coating of WD40 and then wiped it down. He said the WD40 fills the pores, gives it a very nice finish, and makes it very easy to clean if it gets greasy. Just wipe it down, and if you use an aggressive cleaner (a degreaser for instance), when you're done you just shoot it with WD40 again.<BR>
