Got this exhaust from Bill Cathcart for my 185 . It is all cast iron.
In the past I have applied ceramic coating with my detail gun. This coating is expensive. I didn't have much to coat here because these are pretty small pieces. Before coating I took off most of the casting marks to give them a smoother look.
I found some rattle can ceramic(so it says) by VHT and thought I would give it a go. Applied per directions. When it was dry and could be handled (3 hours). I put them in the oven I use for powder coating and according to direction heat for 30min @ 250f let cool for 30min then heated to 400f for 30min, let cool for 30min then heated to 550 for 30min, let cool overnight. Instructions said 600f for 30min but my oven doesn't go that high, its an old kitchen oven.
I am happy with the results. We'll see how it goes after some real world use.
