If the alpine glide slide and simms tephlon can be had to the consumer for under $15.00, how much of a loss could there be ??
Because you are talking about creating an entirely new mold for the new slide and then scrapping the current mold and all of the slides that have currently been produced. If you went with another company's slide then, I would assume, you would have to pay them royalties.
Personally, I think a new material would be the route to pursue.
