How to properly use Glyptal

Well-known member
I have a couple cans of Glyptal , Is it really necessary to bake it at all or is it suitable to apply to the internals of a cleaned engine and not be concerned about it turning loose and causing problems ?
 
I have used Glyptal for many years and it always has worked very well assuming the areas are clean , just brush itr on and let er dry . Have seen engine apart we did many years back and the inside look very good !!!

Seals uneven surfaces in engine castings to improve oil circulation.

Application
Glyptal is used to seal the internal surfaces of the engine block for fastest oil return to the sump. Make sure the surface is absolutely FREE OF GREASE OR OIL! Our Metal Wash concentrate (10120) or PRE Painting Prep (10041 Z) with the Engine Brush Kit (46035) does a great job of cleaning the engine block. Be careful to avoid getting paint on machined surfaces or in oil passage ways. Can be thinned with Xylol or Xylene

Brushed on, it also works like a charm on '32 aluminum oil pans which are porous enough to actually sweat oil. As noted, however, absolutely clean surfaces are a must.
 
I use a heat lamp to help "bake" the parts as they dry. I move it around during the process. You'd be surprised how hot they get parts

How do you absolutely clean porous aluminum? That was always a problem for me when I tried to heli arc weld heat exchangers.

Hi; Just note. while available for electric motor rebuilding and insulating, the SPRAY can versions work also, BUT use Good respirators, not just masks. It can coat your lungs also. Newc
 
Thanks Newc for the heads up , I have spray cans ,I wouldn't have thought anything about it being so toxic, I will make sure I use a respirator. will this stuff work ok without baking it on?
 
I've used Glyptol several times and each time i've used it, i baked it per instructions. The result was hard as glass. I'm getting ready to do the engine cases on my '48 Indian.

Is it necessary at all internally? Wouldn't it be a layer of insulation from the oil, which might be useful for cooling the block as the oil runs over parts and into the pan?
 
It has been used for years in high performance engines to increase the flow of oil over surfaces back to the oil pan. Is it needed in a mild built flathead, probably not, but that applies to a lot of things! I use it.

Also Inside of oil filled transformers.....anyone else remember PCB's ?

I already have it so I may as well use it or toss it out in the disposal site. true Probably not needed but it may help keep the sludge from sticking.
