use the stainless mesh ones

Not the fibre ones.!

Have had trouble with the mesh ones sealing on the heater box to exhaust join.
The fibre just wont join solid.

Changed today to stainless steel mesh and it "seems" to grab much better.

I will say - up until now i had flanges and flanges is the ONLY & PROPPER WAY to do it.

"WHEN" i get some time to pull the motor i will change to flanges.
Until then - this seems the go
