Oval liner, what brush?

[MikeP]

So I relined my chimney with the oval duraliner (rigid liner), and was wondering what anyone else with this or any oval liner uses for a brush? I was thinking of just getting an 8" poly and trimming to size, but didn't know if anyone had a better suggestion?

Went through the same thing. Here is what I did.

Thanks Lobsta, you get the brush? How did it fit/work?

I'll probably just try trimming an 8" to size..l.
