The directions for Bow To Stern say to use a synthetic cloth or foam sponge to apply BTS to my boat. Why is this necessary?
It is only a recommendation that you use these items to apply BTS. The polymers in BTS love to attach themselves to natural fibers like cotton, wool, paper products, cellulose sponges, etc. It wont hurt to apply BTS with any of these items but you will be locking a lot of the BTS’s polymers in the applicator and they wont reach the intended surface. Basically, we want you to get the best results possible out of your purchase of BTS. You can buy synthetic sponges at most dollar stores or you can buy them from us at the BTS store.
