Thank you everyone for the discussion - especially you Jacob! And a note from Vinay <blush> to boot! I am planning on doing this over the next week of a modified H10 semi-folding yurt with vinyl. I found an automotive upholstery place by me which will sell me the DAP Weldwood Landau Top & Trim HHR for $13/qt, but I have to provide my own quart can. I plan on picking this up from Home Depot for $3. The cheapest I have seen it is about $47 shipped per gallon, and although I may need more than 1 qt the shop is right by me and I figure I can always buy a second qt to cut down on extra waste.
I then also have a roll of 60yds BFT to tape the roof cone, tape ring, tarp ring, and then still have extra to boot for anyone who needs it. I will definitely be taking a lot of photographs and can send them to you Jacob to add to your Google Drive for those wishing to do a hybrid approach. Again - can't thank you enough for putting together such a great guide!!! I'm looking forward to how this all turns out!
