I'm shopping around for skin materials for my SOF projects this winter. I've heard 9oz polyester, 12 ballistic nylon, etc, etc.

Most sources I have visited don't deal with oz-weights, but are quite happy to discuss denier-weights. Is there an x-ref chart I can look these things up on?

Also - one upholstery shop that specializes in boat tops and such that I've visited can sell me 11.3oz or 1000 denier cordura (urathane coated) or 11.5oz polyester coated with acrylic. Odly enough their catalog lists different weight units for different fabric types.

Would either of these be suitable, or would anything I painted on them eat them? Given a choice I will lean toward ruggedness in my first boats over a bit of weight savings.

Cost for either of the above fabrics would be $22 CDN (~14USD) per metre, 60" width.
