POR 15

Used POR 15 manifold dressing on my manifolds. Any other users out there. How does it hold up? Says good to 1400 degrees

I used it on a set of 360 manifolds about 13 years ago. I followed their dirrections exactly but it started flaking off shortly there after. Some have said it lasts a long time. Others have had my same experence.

i know thier rust inhibitor aint that great.
