anyone out there have success with a product that will stop two pin-hole leaks in an original '35 radiator without gunking up the whole cooling system?
I realize most stop-leak products are less than advertised but hope someone has used one that actually worked and did no harm.....

If you can find it, try AlumaSeal. It is a powder and works without clogging.

I have used Bars leak and have success on small leaks, you just don’t want to add more if the first one doesn’t fix it. I have seen radiators and heater cores plugged when the they keep adding trying to fix it.

I have used AlumaSeal as well. It used to come in a silver looking, powder form, however what I have seen now it is only available in a liquid form.
I have never had an issue with a radiator plugging up with it, and it worked well until I could do a more permanent repair.

I don't believe in stop leak. IMHO, fix the leak. Its better in the long run.
Having said that, I just bought a tube of Alumaseal last week to get aluminum powder for an experimental paint project. It isn't powdered aluminum anymore. The tube is now silver colored so you cant see inside, and the powder that you can't see is BROWN. It appears to be the same turmeric root or whatever that is in bars leaks and those pellets that used to come with water pumps.

In my years as a mechanic I have found that most of the additive type sealers seal more than the leak and are a very temporary repair and as such I dont recommend them (basically a can of rattle snakes that turn around and bite). Pull the radiator and have it fixed properly, but in doing so you may well find the rest of the radiator is about to leak next week. Do it properly the 1st time and save time and money.

I have put alumaseal in and had great success....but it was for a farm tractor not a car!!! I agree with tonyw take it out and have it repaired at a shop... nothing like running down the road one day after you forgot all about it only to breakdown and worry about it possibly
breaking the block because it got to hot.
