Review: Good product - tested to 750 degrees ! and OK - Great for attaching seal on Kamado Joe Barbeque
Review: Really useful high temp sealant that works very well. - Great high temperature sealant, if stored properly a tube will last you years (writing this review nearly 2 years after my purchase) and its still good with no seperation. If you properly prepare the surfaces by removing all debris and grease this sealant will work for many different applications and materials - if using it on oil pans it is critical you clean the mating surfaces meticulously and degrease them thouroughly, apply a bead and smear it with a gloved finger or plastic spatula and reapply some where it thins out so you get a good even coverage to avoid it blobbing out and don't forget to retorque the pan with a criss cross pattern to make sure you're evenly spreading the torque so the rtv doesn't thin out where there are machining imperfections on the mating surfaces - if you're failing to get a oil pan seal you have a very distorted pan head which is very common, you might be better off using the proper gasket for the pan with loctite 5923 as a liquid gasket and apply this rtv on any joints using the smear technique. I've used it recently as a make shift gasket to replace a impossible to source gasket for a throttle body in a 2012 kia ceed 1.6 crdi that has a EGR and DPF, it's easy to apply with the tapered cap, it cures within a really reasonable amount of time, it's affordable and it has many applicable uses.

## Questions & Answers

**Q: Is this OK with petrol fuel**
A: I used it for the gasket sealer in the cylinder of my petrol/ 2 stroke oil chainsaw and all is good six months later. Mine was however, black and not red although I am aware that red sealer is used on the  stihl chainsaws from new.

### ⭐⭐⭐⭐ Did the job but cheaper options out there.
*by O***S on 13 May 2025*

Used as a sealant for a motorcycle paper gasket, for the price it was OK. It did the job but I think they may be alternative products that would have done it cheaper.
