Pour réparer auto

I got this to adhere my wood stove door gasket in place. The black stove pipe gasket stuff that came with the stove is crap for a skoolie. The original gasket came off so we got a new one and that one was falling off too! To I got this stuff and the segment I adhered with it is rock solid. I have two more jars for the rest of the gasket. Also, less off gassing with this stuff, so win win!

Great value. Build it up in layers as it slumps badly. I am using it INSIDE exhaust manifold so will report fully when job is finished, maybe September 2020!

I never got the full order so I didn't get the coverage I needed for a proper test. What I got seems to hold all right.

used it to repair a small separated seam on my exhaust. i cleaned the area well and used my shop vac to create a negative pressure in the exhaust so as to suck the product into the repair. it held for a couple of days and that was it. with that being said i do feel that this is a good product it just can't stand up to the expansion and contraction from the heat coupled with the vibrations from the exhaust. it mixes easily and goes on thin so with vac it really pulls it in and it hardens well I think that it would be more suitable for a wood stove or grill repair. I would use it again just not for exhaust work.
