That stuff if coming off easily and I think it was also getting diluted with the gear oil. Should I remove the remaining stuff and put another coating? and what kind of "paint" was that? Thanks in advance [Reply]   [Send Email]

I"m waiting for the local supplier to give me a price on Glyptal. I will clean it good and re-evaluate. I know oil is not seeping out of the casting. Rust is a concern though.   [Reply]   [Send Email]

Differential gears sitting in water in the bottom of the housing for several years is another thing, but Glyptal won't help that -- only oil changes.   [Reply]   [No Email]

I've never repainted the inside of a casting.. imho.. I doubt you need to either.. soundguy   [Reply]   [Send Email]

If it wasn't seeping out before you tore it down, it is very doubtful if it will seep now. Just wipe the oil out and leave it alone -- my opinion. I've done 3 transmissions that way.   [Reply]   [No Email]

It is heat resistant and oil resistant. It would be best if you remove what you can and try to locate the original paint, The cast should be covered to prevent rust. The condesation that developes in the gear boxes will cause the bare cast to rust.   [Reply]   [No Email]
