AMD Cowl Panel

I will be doing this soon as well. Perfect time to remove old sealant from the stand pipe tubes, remove any rust that's in there and reseal and paint the lower cowl plenum before putting on the new upper cowl as it's called. Use a good epoxy primer in there like Kirker Duraprime, then scuff and topcoat. You will never have any issues in there again in your lifetime if its dealt with correctly.
