Anybody here used the above mentioned product ?
I applied yesterday some amount of it on my exhaust system in my junky car but my concern is that this stuff does not harden. I left a small blob of the material on the parking lot to compare how it hardens on my car and this morning it had thin layer hardened on the surface but when I pressed harder my finger plunger into the blob, which turned out to be wet and soft inside.
If this is how it works on the muffler system I do not like it! I was in the understanding this is kind of polymer, similar to epoxy, which hardens on its whole volume, but it looks like this is a solvent type stuff which hardens trough the surface evaporation. When the surface hardens, the deeper layers do not and stay soft.
Any advice?
