Hi All,

I am getting my spare block hot tanked and fluxed on fri. I am not going to assemble it anytime soon but am debating weather I should paint with any paint for preservation purposes until such time as I can rebuild it and paint it correctly.

OR, paint it correctly with Ford green paint and then squirrel it away.

My question is what primer should I use-if any? I don't think I did the last time and it is starting to peel off of the cylinders. Is there a high temp primer out there?

Thanks,

Mike

You don't need primer. Wait until the engine work is finished,then paint. I suppose in the mean time you could wipe or coat the block with oil to pickle it .

Is the iron that porous that the paint will soak in and grab?

you do NOT need to primer the block if you are using engine paint. it sticks real good to bare metal.

Don't use any oils on the outside, they will soak into the cast and make it harder for the paint to stick. Paint it now with engine paint, touch it up later.

Yes...What Mark says
Paint it now, put it up, and you're done
Do Not Coat it With Oil

Agree.....paint it with final color now. If you ding it before installing it in your car, just touch up with a small artist brush. The green paint I used from Snyders went over a cleaned up coat that had been on the engine for the prior 25 yrs or so. No chipping or peeling since it was done three years ago.

I definitely agree with painting the block now. The problem with waiting is the porous cast iron will absorb oils that come in contact with it and that will lessen the paint bond.

I build engines. I caustic clean, steel bead blast and then paint immediately with Snyder's Antique Engine paint. After machining they are degreased, completely scuffed with a 3-M pad and then a second coat of the same paint is applied. There is no problem with adhesion. I would do the same if storing a block.
Good Day!

Thanks for the responses. I think I will have to dig out my paint. I hope I have enough

I have found that Snyder's Ford Engine Green covers very well and is dead on to the original color. Shake the can well. They offer it in rattle cans or half-pints. Get the half-pint. Mixes better.
