: . . .I'm not trying to be the coating police... honestly curious about
: possibly easier-to-get alternatives to Goop, Zar and Coelan.
: Makes me wonder what the specs for other coatings looks like...
: I reckon you don't want to get those in your eyes or set them on
: fire, either, lol! : )

How many coating choices can you handle? There are a lot of them. Some work better with one fabric than with other fabrics, or some fabrics just don't work with some coatings. but the list is long.

To start with: Paint. Lots of people use exterior house paint: latex, acrylic, oil. There are also enamels, urethanes, polyurethanes, varnishes, neoprene, hypalon, natural latex rubber, and elastomeric rubber roofing material.

if you want to go with thicker materials you can use a squeegee to coat fabric with silicone, acrylic, or urethane-based caulking compounds.

If you are really oldschool, the only thing would be to use pine tar-- which dates back before 1000 AD, but can still be seen on some Irish curraghs. (I hope I spelled that right) George Putz has a picture of one in his book on canvas covered boats. If you want to stay "natural" you can use boiled linseed oil with an added dryer.

Beyond that, you can whip up waterproofings from lots of polymerized proteins. Even gelatin can be made insoluble by adding potassium dichromate, or ammonium dichromate, and exposing it to sunlight to a strong UV source.

After that, just about anything which can be dissolved in a petroleum-based solvent, but not in water, has probably been tried. Paraffin-based wax dissolved in naptha or gasoline was used for years to waterproof canvas tents. Terrible fire hazard, though.

The list of "possibles" goes on and on. But the list of "great" coatings is fairly short.

Good luck with finding one you like. Write back and let us know how it works for you. Or, sned out a query about one particular coating you might like to try. People here have probably already given it a shot and can let you know how it worked for them.
