The son and I are getting ready to assemble a Brinkmann Trailmaster, we picked up at the Home Depot.

Over the years, I have occasionally read about the use of Automotive High Temp Silicone to seal gaps between the cooking chamber and side fire box. When I change a thermostat or water pump on my Cherokees, I use the red Permatex product, which smells funky. I can't see how that stuff would work in a high temp situation such as a fire box, without producing some harmful/toxic fumes, even after it cures.

Can anyone offer some advice and the pro and cons of using this product.

Thanks
Joe :)

Joe, what about asking a fireplace specialist for a sealant recommendation?

Thanks for the reply. I was looking thru another BBQ Forum and saw that someone had posted the same question. One of the subscribers had recommended using Permatex "Black", but another party posted a link to the web site "BBQ Gaskets.com".

I will probably pursue the gasket trail, since it will should be a much neater installation.

This all started because after my son and I assembled a Brinkmann "Smoke 'n Pit", we noticed the gaps between the upper and lower portions of the smoking chamber. We thought we had done something wrong and after a call to Brinkmann discovered that the unit was designed with the gap. This was different from the older Brinkmann design and we wondered how the unit would be able to maintain a productive temp, without all the heat leaking out. Coincidentally, one of the local Home Depots had a Brinkmann "Trailmaster" on sale and since the "Smoke'n Pit" was never used, we returned one and purchased the other.

So we figured that the assembly of the "Trailmaster" would get off on the right foot, including a better seal between the cooking and fire box areas, around the lid lip, relocation of the chimney, etc.

Here is the "Smoke'n Pit" back at the Home Depot, sitting pretty waiting for some unsuspecting soul to adopt it. Sorry about the pic, couldn't figure out how to resize it.

Designed with built-in leaks...weird!! Glad you were able to exchange it for something better.

Joe,

Here is a link to a previous thread concerning how to seal the leaks.

viewtopic.php?f=2&t=19481

There is a link to where I founds the gasket that I used on my Chargiller. If you scroll down, there is a link to a silicone sealer that I picked up from Ace Hardware. The one I used is the one on the right side of the product page. This stuff has held up for 4-5 years at least. Hope this helps.

Thanks for the replies and tips. I will check my local auto supply stores for the copper Permate.
