undercoat above exhaust

[Trogdor636]

So I recently welded in a new section of floor above where the y pipe meets the mid pipe due to a small hole starting to form in the floor. Is there a undercoat that can be applied above the exhaust? In the cab I am just going to seam seal and use a high temp primer, but I was looking for a little more protection underneath. Thanks folks.

Seeing how bedliner is thick, couldnt you apply some down there, also preventing rust with it, or no?

I'd honestly use a heat shield made of thin metal to bolt above it.. Just my two cents, but im sure it'll help.

Bedliner was a thought, I just was seeing if there were other options. Does bedliner hold up well to heat?

Try manifold paint, or even barbecue paint.

I have some high temp primer (rated higher than manifold or bbq paint...like 2000 degrees!?!?) I was gonna hit inside and out. I was wondering about the undercoat because that would help cover the patch, you'd basically never know it was there. I might just try it and keep an eye on it. I'd prefer to not be a rolling fireball.
