Done a search,couldnt find anything.This is probably in the completely wrong section so if a mod can put it where it belongs.Thanks

Anyway,with all these amazing builds going on im seeing endless amounts of immaculate engine blocks.Basically i want to now how to do it? Surely someone has a how to thread up or something.

Used an aluminium cleaner on the block but its now got the whitish aluminium corrosion back.

Any info much appreciated.

Thanks in advance

 

glass bead blast it or

use brake cleaner, degreaser (with a wire brash), pressure wash it and spray it with some aluminum engine paint
