Here's my .02 and I'll raise you .02
Henkel Chemical makes possibly the best modern day water based contact cement for tweed & tolex work.
This product is sold under at least 8 different popular brand names including Formica Corporation ( F160 Adhesive
What sets this apart from other alleged safe water based products is the absence of Toluene
in the formula.
Toluene has a very distinct thinner odor, if you ever buy water based brands like "DAP" or Weldwood you will smell it.
Another of the Henkel Chemical formula brands that is fairly easy to locate is HYBOND 30 Natural
Identical to Formica F160.
Hybond typically costs $170.00 for 5 gallons
Drums are real cheap, but expensive to ship.
These are Greenguard
certified products and do not give off nasty fumes.
If you ever set a gallon of Mojo & Hybond next to each other and take a quick smell, I think you will agree they are likely the same.(except the price)
There are other numbers on the empty 5 gallon can I have here, but searches on Henkel's site turns up nothing.
I originally got the brand info from a Henkel Rep when the Formica Corp dealer here stopped carrying the F-160.
