    Hello,

    I am building a SOF F1 kayak and i'm almost done. I am looking for a supplier of ballistic nylon in the EU so i can finish my build and skin my kajak !! :) The ballistic nylon would prefably be untreated and have no dye . If there are any other good options you have tried beside ballistic nylon let me know.
    Can anyone help? Thank you

    I have been using polyester fabric and coating it by thinning silicone sealant and painting it.

    Are there any pros with using polyester for skinning a kajak compared to nylon? And what type of polyester do you use?

    The stuff from extreme textiles has a rather large open weave, compared to some others. I have built a kayak and a sil canoe from it, it does work, but it also relaxes quite a bit when wet. It really needs fitting damp and stretched as much as possible. There is a guy in Poland selling better fabric by the name of Marcin Bobber, he can usually be found on FB groups with anything to do with SOF.

    I used ottertex.

    I think the main advantage to polyester is a lot more stuff bonds? So you can paint it with a lot of different things and patches stick better. Nylon maybe more difficult to glue but it stretches more so it could be more durable??

    I had one in the past that used hypalon, but this ends up being near $100 per meter. This is very durable though.

    Good to know. I'll make the skin damp before fitting it over the kayak.

    I used a spray bottle and a "mist" pattern. The real issue with that particular fabric was trying to keep it under tension with stitches while damp, as the material weave really opens up. I had less issues on the sail canoe as i could staple the skin all along the gunwhale at close intervals, where as the Kayak had a rolled stitched center seam. I would reccomend a practice run on an offcut, just so you know what to expect. I can find some pictures if it may help

    I believe that is the case. It would be "false advertising" if not, and they have been advertising the materials for many years.

    I cant locate my Mobjack build photos (on another system). I will post them when located. The canvas pliers tool is really worth finding, cheap and worth it even for a single build.

    How about aircraft fabric. Glues on easily and shrinks smooth with an iron. Paint it with the pink primer and it is airtight, use the silver intercoat for U/V protection and then paint. Can't remember the price (And there is a lot of fabric in wings and tail plane!)

    really interested in using multiple layers but cant find a lot of information. Also worried about water between the layers.

    What about spectra/dynema uhmwpe fabric?
