I suspect I may have coolant seeping out through the head gasket. No water in the oil; just coolant on the side of the engine. Has anyone had experience with chemical sealers?

I have seen this issue before. Coolant leaked from head gasket when first started, but would quit leaking within a minute as soon as some heat got in the block. I tried some liquid sealers, all it did was plug up my radiator. If the leak is not that bad, try and live with it. Gary

Bars Leak Head Gaskit repair. Liquid stuff in a bottle. As I recall there were two types, one type mixes with anti freeze, the other type does not and you have to flush out all the anti freeze first. The one that mixes with anti freeze is a lot easier. As mentioned it did plug up my radiator and probably my heater core. As Jody says below fix it right, or try and live with it if it is not that bad. Mine has been leaking for two years and has been no issue at all.

Oh please don"t use that stuf. Bought a car that had that used in it. Had to toss the entire cooling system. If it's leaking bite the bullet and fix the problem correctly. ALL the quick fixes to that sort of problem are just a disaster waiting to happen.

Just my 2 cents worth here: When I disassembled my early '73 (rope main seal), the one known problem was an internal leak in the cooling system that turned out to be, as expected, the head gasket. However, upon cleaning, it turned out that the leak had been present for a long time and coolant/water was entering two combustion chambers, turning to steam, and causing corrosion around the exhaust valve seats, pitting the head casting. I suppose if the condition had gone on long enough, a seat might have come out, causing, well you know, a mess. What the pitting did do was take away my intention to build some kind of gee whiz, high compression go fast machine. Not possible with the pits. They become hot spots and/or a collection point for carbon deposits that in turn become hot spots. Either way, high compression and hot spots equals detonation, spoiling my fun.
