We all get those small nagging leaks that are annoying and sometimes expensive to fix. I'm talking about things like oil leaks around a pan gasket, or leaks between two exterior fittings of some sort. I had similar leaks on my 1996 Cadillac (pan gasket), and my 1928 Chevy Coupe (torque tube to U joint bell housing and axle tube to bearing housing). They weren't bad leaks but one (the Caddy) was really expensive to fix since the engine had to be jacked out of the car to remove the pan and replace the gasket. The 28 leaks meant some major disassembly also.
On a whim I tried Leak Seal from Rust-Oleum on the Caddy pan gasket before a trip to Florida. It worked. When I got back I tried in on my 28 Torque Tube/U Joint leak-it worked too.
Here is how I did it. Some trial and error so not successful on first try. Clean the area thoroughly of all leaking fluids (may require some drying time). As a final step, clean the area with Denatured Alcohol as it evaporates quickly and leaves no film or grease as might happen with Mineral Spirits or Turpentine or other cleaners.
After the area is clean and dry spray a light coat of Leak Seal on the area-overlap the leaking area. Let it dry thoroughly (overnight suggested). Then go back and give it a second coat and let it dry. I'd spray a coat on in the morning, and before I left to go home I put another coat on). Do this until you have built up about 5-6 coatings or more. Do not use heavy coats.
NOTE: You can't use it for everything so use your discretion. It may work externally on a small water pump leak but you can use it internally in the pump, or in a radiator, or .........
Since Leak Seal is a flexible coating it can be used in areas where there is some flex going on, like my torque tube. Although designed as a sealer for water leaks that can withstand some minor pressure, it works well on my cars (so far anyway after many months of driving). The only downside is you can't drive the vehicle while you apply several coats over several days.
It only costs about $6-10/Can. You might say it is similar to that stuff they advertise on TV, only a lot cheaper, a lot more to a can, and a lot better based on what I've read about the other product. It is worth a try before engaging in costly or time consuming repairs. Don't know how long it will last, but so far so good, and at least my wife lets me drive my 28s into the garage since there is no more 600W dripping on the driveway. Only my wife would care about an oil spot in the driveway.
