Exhaust Paste

[brainbug007]

I'm just wondering if anyone can describe a bit how this stuff works? I'm planning on using the cheap flexible exhaust tubing to go from my manifold down to the silencer to get me thru IVA & until I can afford to have a nice stainless system made up. So I'm thinking using some of this exhaust paste along with some jubliee clips to join the flexible hose onto the manifold and silencer. Will this hold up ok and further down the road what is the paste like to get off?
