I have found a small plastic bag containing two plastic tubes, each about 1/8th of inch in diameter and 2 inches long, two transparent, flexible plastic discs about 2 inches in diameter, and a screw-cap metal tube of some substance with no label other than the contents and health warnings, viz:
MEX 49.95%, Toluene 0.05%, acetone, 10%, polyurethane 30%, ethyl acetate, 10%
then there's a whole load of stuff about it being harmful or fatal if swallowed etc.
Dez thinks it's a tent-mending kit.
