Originally one idea for the supereasy DIY rack was to pit J-B Weld against PC-7 Epoxy in a no holds barred deathmatch of destruction. The J-B Weld died a quick and painless death. Perhaps PC-7 will do better...
The consistency of PC-7 is very different - more like roofing tar. Pasty, but kinda stringy too, and without the nice surface tension that makes the "fillets" look nice. Definitely lumpier. It also takes way longer than J-B Weld to dry/cure. Overnight at least, and 2 nights would be better.
Stay tuned for the stress testing... Can it hold a 30-pack? On the trail?
