I don't know, I'm very skeptical of this. In all honestly, the 'cost effective' and 'urethane ass slapping list' they have in that link get me thinking it's just a sales ploy. I'd like to see a kit made of it though. In all honestly, companies like Wings West that do millions in sales would have used this in their kits to make even more money as I'm sure that technology has been around for a long long time.
I'll stick with my urethane kits myself. I like how they say in their list that urethane is not repairable YET in the paragraph above it mentioned that 'sometimes' it can't be repaired.
