Good stuff, works on just about everything. I have a pressure pump down by my creeks that I use to water my property and the housing developed a crack that was spraying water. I put some J-B Weld over the area and no more leak!!

Yes, I recommend this product.

I have been using J-B Weld for 50 years. It has NEVER failed!!!! Most severe use....in about 1976 I used J-B Weld to seal a crack in a car engine oil pan....455 Olds V8. I owned that car until 2000, And the repair held for all that time!!!

Yes, I recommend this product.

Rear end repair

a year ago

Fixed a rust hole in the bottom of a semi truck rear end. It was about the size of an ink pen. Drained oil & used a grinder to get all the excess rust off. Applied to an area 6x6 square. Left it set 24 hours & refilled with oil. Painted over it once I saw it didn’t leak. Probably 50-60,0000 miles & no leaks. Worth every penny. Update, a friend has repaired his the same way, no leaks either.

Yes, I recommend this product.
