It seems to me that the "inventors" of this form of plastic would have aggressively tested the material before putting it into production. They should have a pretty good idea what the typical life expectancy is for their product. Does anyone have access to this sort of laboratory data? =============== Considering the product's operating environment it's remarkable that plastic kayaks last as long as they do. The variables are duration and degree of UV exposure, something the maker has little control over. Try googling "polyethylene UV exposure" and you'll get a sense of the difficulty is accurately predicting product life. --allan *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
