Powder coat your trailing arms, beam, x member etc.

I painted my block, pulleys and rocker with rattle cans, but put a high with a temp lacquer over the top. However the engine hasnt run yet but my mate who is a painter done the same (in white) and his still looks awesome some fews years later.

Interested in the comments on the diff as i still need to do mine and the gold bit on the drive shafts.

Good luck fella, where is Soton you from? You a scummer like me?
