I used this on a corning glass lid with a ceramic knob that screwed into the lid with a porcelain piece on the underside. Only took a small amount, around the threaded part and a tad bit in the hole of the top knob. I left it to cure for 2 days and cooked my chicken at 400 degrees gas stove. Worked great.

Dose what supposed to do, used for temporary fix on exhaust system, held up until pipe was replaced, no complaints.

I still did not have the chance to use this specific solution from J&B but knowing J&B product from previous use, it works great !

Works good for small leaks if applied properly.

It’s always good to have around for cheap repairs

I prepped the exhaust as it should. The putty did not even last a minute .exhaust pressure just blew the repair spot off .

This is a great product from a functional point of view. The only on site problem has to do with cutting the desired putty out of the protective plastic surrounding the putty mix. Cutting the plastic is troublesome and removing the plastic from the putty once cut is troublesome.
