I believe either Foretravel or Cummins recommended Bars Leak event if you didn't have a leak.

If the leaks are seeping or small, I've had excellent luck with a few tablespoons of cayenne pepper. This article recommends black pepper but I have always used cayenne pepper. Pepper is too small to clog anything but expands where a leak goes to the outside.

J.B. Weld is great for cracks you can see on the outside. They have fast, slow, high temperature, etc. The original is slower but the strongest. Good to have the area clean and perhaps a little acid on a Q tip before applying the J.B.

When I first got my coach, I found out the radiator had a leak. Tightened the bolts holding it together that I could reach and used the Barrs. Not a leak in 4 years.
