HST Wine, Not any more

I used to work in polyurethane (foam) roofing. That operation had a guy in the shop that also did tractor tire fill. Mostly for Mobil home assembly lines. The workers would put a nail in the tractor tire to stop the line. With foam in the tires the tractors would keep going after the rubber was falling off. This was in 94 and I believe they were charging $1500 a wheel. Now they used a denser mix for tires than roofs. I'm not sure how they archived the desired denseness. I think it was changing up the part. Part b ratio. Anyway my point is it they can fill tires through one small stem hole I'm pretty sure a rops could be filled through several holes. It's just a matter of having the practice knowledge of he materials. Tiger foam sells a 2 part kit for like $500. It will cover 700 sq ft 1 inch deep. It's pricey but thear is another option, having a foam shop do it.
