I am looking for something to make coil repairs with. Non brasing, non soldering.

I dont have a problem with making coil repairs. I have been sucessful using the low temp solder kit on ALUMINUM. But my skill is best in epoxy repairs.

I have a tremendous sucess rate. But my holes to patch have usually been small ones.

I would imagine that with all the breakthroughs in chemistry today, we would have something we could simply clean the pipe, paint this stuff on, apply either some heat or a second chemical to for a reaction like a catalyst ...then it's ready to return to service.

Has anyone found something simple and sucessful?
