Okay my turn.....
I've read this whole thread and I either missed or didn't see anything about a Viscosity Cup.
This would help with the mixing by timing how fast your mix goes threw the cup. Then you will be able to get it the same every time and that will help in the drying time too.

sounds as if getting the air out via vacuume makes for a better seal and stonger bond. I'm learning so much here LOL.

After the Mods save this thread and lock it, can they up date it with any result from members who
want to ad new findings that will help?
I want to try some different things I've read here
but it won't be until this summer.

BIG MOPARTS KUDOS to all you guys who are trying this and to
69Charger for letting us in on this.

Now if it works on my Dart Sport, I have my eye on the gold 71 Scamp survivor in my garage.........just kidding.
