I am replacing the head gasket on a 4020. The block is missing a lot of paint (the other side is much worse), I would like to paint it to improve it's appearance. The block is still in the tractor, there is no plan to remove it.
I plan to wirebrush the block leaving whatever paint wishes to continue to stick. I will clean off all the oils and then prime and paint. I plan to use JD primer and then overcoat with JD green, all from spray cans.
My question is, will this adequately adhere to the block? Any comment?
Another thought would be to coat with that Rustoleum paint that bonds with the rust and then prime and paint it. Again, any comment?
Attached is a picture of the block.
