Paint: Glyptal Paint Question....

[DEEPNHOCK]

Glyptal paint question....
My block has glyptal paint on it already... Except where I have been grinding.
Can I 're-paint' it all...or should I just touch it up?
(at $50 a quart, I'd like to know beforehand)...

Touch it up or leave it, it's not that big a deal in the overall scheme of things. It just speeds up oil flow back to the pan, and a few bare spots should not be a issue.

True glyptol is the tough insulation coating on copper wire in things like transformers.

FWIW, Stude painted the blocks to prevent rust in the midwest humidity. Very few of the pro builders I know bother with it. I know I wouldn't put paint inside an engine block if you gave me the $50-a-quart paint.

Locomotive diesel engines have the inside of the blocks painted for the reasons listed in the above posts. We use the Glyptol paint on the inside of the main generator and traction motors. I wasn't aware that Studebaker painted the interiors. I'm not sure of the nessesity on automotive engines, but I don't think it could hurt.

FWIW Dept;

Studebaker did not use "Glyptal" per se.

They used SYNTHETIC CRANKCASE SEALER, part number 8070, paint symbol XXY and their supplier was O’Brien Paint Company (of South Bend).

Studebaker Engineering instructions read as follows:
"Paint cylinder blocks inside surface, except machined surface" (with 8070, symbol XXY)

If the can's never been opened...just grind/sand the valley chamber and everyplace else that you can reach smooth (straight and or right angle air grind tool) with 60grit sanding discs.
Accomplishes the same thing, much cheaper, monetarily anyway.
It cleans any surface stuck sand, rust, loose paint, and provides a quick oil drain back when using 120 grit discs as a final (semi) polish.

This what I did to my block.
