I've used Eastwoods coating on multiple cars and it has lasted quite well for me. The preparation is very important. You need to sandblast the manifolds and clean them with laquer thinner or equivalent before applying the Eastwood. You can also use a stiff wire wheel on a hand grinder if sandblasting isn't available to you. With that method, I would also use some "Metal-Prep" (or equivalent) to get the rust in the pores. I use the "brush-on" coating - never tried the spray!
