J-B Weld SteelStik Epoxy Putty 2 oz Gray

I used it once before to seal the leak on my car's radiator, located near on the top. It lasted until I traded the car. Then I decided to use it to fasten the nut on the bolt that holds the bottom of the rear strut on my 14 year car. It lasted 2 years before it came off. It probably would have held better if the surrounding parts were not rusted, and/or if I used more to enhance the durability of the adhesion. ( used 2 sticks)

GREAT product!! This wizardry fixed the BROKE IN THREE AREAS bike frame of my 16 yr old grandson. That joint that the seat sits and branches out to both wheels and frame. I would think one of the most integral places of a bike frame. I sanded the area down, cleaned it WELL with spray Dawn, then did a good twice over with 99% alcohol. Smoothed it all out to look a least repaired as possible..lol. Lol more sanding with 1000 grit...and was able to even 'match' the wine color with some nail polish and a nail shellac top to prevent chipping. etc. it looks like it never happened AND has held up just as well. We'll see how it holds over the longer terms.
