@Squick18.10.2023 15:11MemberI am more inclined that in this condition it is better to sandblast and powder paint if it is possible. This is what will actually last well and for a long time. Everything else, in my opinion, is not durable and everything peels off.- @user_19280718.10.2023 22:06@SquickMemberReally useful advise, thanks!I was hoping of using an aluminium deoxidizer but...not sure it will pay off
- @user_19280719.10.2023 22:41MemberI have a homemade sandblaster that I may test (perhaps too hash on
aluminium?). I got a quote to vapour blast (more gentle than pure
sandblasting?) all the 9 piece of the engine (including the engine
block) for £200 (no idea if it's a good price or not).
Hi all,
I’m looking for some advice on how to clean and paint again
an aluminium engine block (close up photo of a couple of pieces
attached): it seems oxidized (is it oxidized? Not sure what the white
stains are).
Project is to make a showcase piece.
To clean it I’m thinking about using:
– first pass: Gunk 6868 5L Ultra Engine Degreaser
– second pass: White spirit
Good idea?
To repaint:
–
I would like to avoid sandblasting or vapour blasting it (too
expensive), so: would the paint stick to the stained aluminium as per
photos?
Any advice it would be really appreciated!
Thanks,
