For All the Nayers.., Here is the Slayer

[Henry K. Lee]

Pre 1975 Volvo's for the most part all had Gyptal coating applied at the factory on the inside of the engines and transmissions. Now you know why they have broken world records on the most miles. Applied correctly it will not insulate but cause a non-stick surface to prevent crud build up.

People have ask me for years how my engines are painted on the outside because my paint never peels off. Surface prep is the most important. Sand blast the outside after sealing very tight, Scratch wheel on a drill, Wash with mineral spirits 3 time with a solvent wand. Let dry in the sun, blow dry, wipe masking areas with lacquer thinner, mask, mist coat with high engine primer, paint. Let cure for 2 days. ENJOY YOUR NEW CLEAN ENGINE FOR MORE THAN A LIFE TIME!

My 1926 Franklin Coupe has the inside of the engine block, the inside of the transmission, and the crankcase covers coated with red glyptal to avoid oil leaks due to porosities in the aluminum castings. This is an original car that has never been restored. This was quite common back in the day, to avoid oil leak complaints from customers.
Even on modern jet engines, most aluminum castings have some type of epoxy coating on the inside for this exact same reason.

Hank, we, in Texas, have been having a record setting hot summer so far. I know other parts of the U.S. are having likewise. We have already had at leat 14 or more days where it has hit 100+ F. I don't have an oven (even my wife's kitchen oven) big enough to put a pan into. Will Glyptol cure OK in 100+ F sun at least 6 hours?

It will cure just fine!!!!!!!!
