Chris - search here and go to the forums at iboats.com and search on
vinyl, dye, paint, etc. You'll find quite a few posts from people who
ave done this. Evidently there's spray dye for vinyl that actually
soaks into the material (with proper prep) and thus stands up to
flexing, etc.. Some companies actually make a spray prep substance
that makes the dye soak in better. I've read on that forum several
accounts of durable, good results. It might be worth a try. Also
search the same terms on the net to see the products available. Good
luck and post what results you have.
