[Sledge]

Folks:

I've taken off the right side pipe of my BDR with the intention of trying to get a tighter fit between the header and the side pipe (this is a slip-joint arangement). I've purchased the pipe-expanding tool, and I'm trying to do this without taking off the header.

Do you have any solvent recommendations for cleaning off the "ceramic mud sealant" that was initially used? I don't have a lot of room to work with and I don't want to foul up the aluminum ceramic finish on the headers. I've been thinking of using a wire brush where I can, and maybe flexible sanding paper "tape", but I'm afraid it will hurt the header coating and I want to avoid that.

All recommendations appreciated!

Thx

Bill
