Product Overview:

Description

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.

Safety Information

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.

Reviews

Rated 5 out of 5 by from Using Glyptal Enamel Glyptal 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.

Rated 5 out of 5 by from Good paint This paint is fantastic but very hard to find, I’m glad Eastwood stocks it other companies websites that stock Glyptal aren’t near as user friendly

Rated 5 out of 5 by from Glyptal and Eastwood One can lasts for years unless your a professional engine builder, but if I am building a motor that has never run, I would not build it without Glyptal. If you take the time to measure the difference between with and without, you would never question it again, and Eastwood said 7 to 10 days delivery, I had it in 4

Rated 5 out of 5 by from Better application technique is to dab it on. Very much as advertized. Flows well, does dry surprisingly fast. Will run if applied heavy, and i find the best brush technique is to use a round small craft brush and dab it on rather than brush it on. Leaves no brush marks and flows out well when dabbed on.

Rated 5 out of 5 by from Glyptal Red I used Glyptal to seal my porous and leaking magnesium rims. It seemed to work well in this application. Glyptal recommended it and Eastwood to purchase it from.

Questions & Answers

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.

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.
