Appreciate this info ... Sarasota is a long way from Victoria, so unlikely that I can utilize his services, but perhaps he will have some ideas on what could work. I think that actually the UV has been fine on it - there are almost no flaws in the LineX - one small crack and one small blister, less than sliver dollar size on a 15'6" x 18' surface area ... the problem is really the color that just heats up like crazy in our sun - impossible to walk on without shoes, and not a great color choice in general.
Appreciate the info on other similar products being paintable ... maybe I start with a test area and hit it with a bunch of different things and see how well it stays on!
Great info from all! Thanks again!
