Unless your planning on doing this say every oil change I wouldn't bother. Longest life will be had with regular use. Short drive cycles and letting the van sit will also mean the exhaust will rust from the inside out. At this point it is most likely a Dansk brand exhaust so in addition to rust there will be flange failures or the pipes themselves will crack usually in the bend just after the flanges. Just use good hardware and anti seize so the parts are easy to change when needed. When the engine pipes need replacing consider going to the 86+ exhaust. Changing the rear mount casting will also allow you to use the later muffler and supports. Dennis

So while I'm under the bus working on the clutch I had an exhaust issue to fix (rusted through at collector). The headers are crusty but not close to rusted through. I'd like to paint them with a POR type paint - POR has a couple of High temp options (Black Velvet and POR-20 Aluminum) The first rated for 1200° and the other for 1400° - the aluminum says it is salt an weather resistant. So the Aluminum sounds like it fits the bill but POR says to use regular POR-15 (as long as the parts don't exceed 450°). I think they didn't catch what I was asking them :) Anyone ever used the aluminum stuff? Or other products? Thanks, Jeff '85 GL (Gertie) '78 Bus (Melissa) Patty's Bus |
