Multi-Purpose Glyptal® Red Enamel seals uneven surfaces in engine castings to improve oil circulation
Acid- and oil-resistant
Also resists moisture, heat dust, salt spray
Anti-corrosion protection
Glyptal 1201 seals the rough interior castings of engine blocks to help prevent engine damage. Sealing the tiny pores left in metal after bead blasting leaves the engine block interior smooth and clean, and that helps keep oil clean and flowing freely.
Always use in a well-ventilated area, and always wear eye, skin and respiratory protection.
Application Tips
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.

BulletproofI used this product 50 years ago for the same reason you’re selling it for. Goes on ez, adheres like glue, wears like iron and has a high dielectric. Used it on engine blocks, DC armatures, stators, field coils.
GE was the original maker back then. Bulletproof.

Great product.This product works fantastic. I made a custom baffled oil pan. Used it to seal the steel pan and also used it to seal the exterior of the aluminum engine block. As long as it is mixed properly before using, it is very forgiving and can be applied multiple different ways.

Using Glyptal EnamelGlyptal Enamel went on very easy, and lays down nicely on cast iron which is what I was using it for. It enables oil to come off housings and blocks more efficiently than as cast surfaces.
How well does this hold up/can you add it to diesel engines for coolant and oil passageways? I say specifically diesel because of the coolant cavitation problems that can happen over time, would this help to prevent that, or be a sacrificial layer?
Asked by: Jolly Rodger
I cannot provide you with any advise as I've never used it on a diesel

I read that Glyptal should not be used in the oil pan of an engine. If it is seals engine inside the block, oil flow side of heads, inside cast gear cases, Ect... Why is it not recommended inside an oil pan.
Asked by: CShutt 49
I am original offer. The oil pan in question was rusted from sitting. The engine wasn't ran for many years with very low oil in it. The oil pan I am specifically asking about will only be ran 15-20 times a year. I have cleaned and removed the rust from inside the oil pan to which I am considering coating with Glyptal. I am looking for any cautions or concerns against coating the inside of my oil pan.

Do you install the bearing and bronze bushing before or after the glyptal. Since you have to heat the cases to drift bearings and such in place with a torch.
Asked by: Triumpht110
Would install the bearing and bushing before as the glyptal paint may interfere with the bearing installation.

Is Glyptal 1201 resistant to gasoline? Can the inside of the intake runners of a cylinder head be coated so as to seal the epoxied intake runners from exposure to fuels?
Asked by: Nation
I would not recommend it. If runners are too smooth air/fuel atomization will be difficult. This is more for oil valley areas with less volatile conditions,

Is there a "time window" for baking? Does it have to be wet when placed in the oven?
Asked by: Tony k
Glen at Glyptal said you must be careful to allow solvents to be released or "Flashed " prior to bake.
** Hazardous fumes in oven, Possible blistering etc **
That can be between 30 minutes to an hour depending on film thickness.
Then you may bake at 150 degrees Fahrenheit for serval hours.

Can it be used on smooth surfaces I smoothed most of the inside of the engine but there's a few places I can't get to now I want to go ahead and coat the whole thing
Asked by: Eddie
Yes, this can be used for this application as long as everything is thoroughly de-greased.

Is there any data on thermal properties? It is called thermal paint so will it help keep intake manifold or air flow cool if I coat the underneath of the intake manifold before installing the manifold?
Asked by: Mike
Glyptal has been used to coat the inside of automotive engines to seal the porous cast iron to promote better oil flow. We have no information available pertaining to Glyptal's thermal barrier properties. We recommend you contact Glyptal @1-800-GLP-1201 for details on Glyptal products.
