Review: Pour réparer auto
Review: 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!

## Questions & Answers

**Q: Will this work on a outdoor grill handle?**
A: It should be fine for that application, though I'm not totally familiar with the temperatures involved. I've used it on automotive exhaust applications and if you take the time to sand the pieces and clean them before gluing, it's held together pretty well pretty well for me.

**Q: Can it withstand gasoline?**
A: To use this product, the area of adhesion must be clean and dry. When cured, it should be able to seal in or out most liquids.

**Q: Will this work on stone?  I have an outdoor fire pit with stone façade falling off. Mortar breaks down under heat**
A: Product holds up well in high heat. Success here depends on weight of stones. Will adhere.

**Q: Is it really 2400° or is it only 1000°. Just bought one on Amazon and it clamed to be 2400° but send one that was only 1000°**
A: False advertising! The product packaging clearly states 2,400 deg in the picture on Amazon but when it arrived the packaging stated only good to 1,000 deg. I did receive the same product # 37901 but it is definitely packaged different than advertised. I picked this seller because the product was to be used on a ceramic grill repair and I wanted the highest temp product and this seller had what I wanted. At least other sites having this product advertise it with the correct packaging and wording. I have to decide if I return or attempt grill repair. I want to use grill this weekend and hope I never need to test the products ultimate strength. Buyer beware!

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!
