Well this is a bit disappointing. I took my heads and intakes to be hot tanked and the finish on the intakes is now quite, er, horrid really.
Previously I had scrubbed them clean and kept the silver finish. They looked stock but fairly clean (as clean as I could get them with petrol, a stiff brush, and some furious polishing. The point of getting a shop to clean them was to bring them up better than I could.
In all honesty they looked better as I had got them. Now they’re plain and have to be coated or painted.
Any ideas what I an do to get them to a factory (ish) look? Just silver paint and lacquer? Do they need high temperature paint. Power coating maybe.
I would degrease them, etch prime, then plain silver and lacquer but would that last in the hot engine bay?
And do I have to mask the injector bores, etc?
First 2 Photos show how clean I got them and next ones show how they look after the shop got hold of them. I think they actually media blasted them. Not sure. They thought I had done a good job and maybe they had to blast them to get them “better”.
