Looking for suggestions from you experts

I posted this in the main area but I realized that they probably don't have Tuff coat outside the US.

I have a 1996 Nautica 18' Deluxe rib that I've been restoring (former Navy rib). I have it re-powered and everything is working great. I love it! The only persistent issue is the poor condition of the hypalon tubes and the rub rail. The tubes leak some air after a day and don't look very good either. It looks like some kind of plastic was painted on the tubes for small wear patches at some point in the past. There are lots of small hypalon patches as well and the tubes have been casted from the inside with some improvement.

I can't replace the tubes (out of my price range) so I've thought about applying tuff coat paint and/or wear patches to get it looking better and maybe help with the many pinhole leaks.

I also should probably replace the rub rail as it looks terrible and the top 1 centimeter is pulling away. (It works fine though and isn't coming off any further after a year or so).

So...Wear patches? Tuff coat paint? Something else? Replace rub rail? What should I do and what order should I do it in? Thanks in advance.

In know where there's a bench that would look good on that one.

Ha ha! I'm actually pretty pleased with the interior layout for what I do with it. Thanks though!

For the rub rails, Kiwiboyd (on this forum) has said he has a decent selection. Hypalon, too, as I recall.

As to what to do, well, those tubes appear to have had some abuse. They're never going to look pretty. If I were you, I'd replace the strakes, and remove and repatch any of the patches that are in the least bit loose. Paint may be in order, depending on the condition of the outer layer of the fabric (if the hypalon layer is sound, you can skip it, as it will not really do much good.)

Order would be patches (as that's the most important), rail, then paint (as the rail probably won't stay on stuck to the paint.)

My opinion only; I'd bow to anyone with a differing opinion (and a good reason for the difference.)

Jky - I have no experience of paint but when you say painting sound fabric does not do much that differs from the thread here last week 'why don't more people paint tubes' ... I suspect those tubes are nearing end of life - would paint add a bit of protection even if fabric is sound?

i would sugest making sure you stabilize your tubes before you paint. replace old patches with new ones and make sure it holds air. if you have any questionable areas cover them in new material. once you are sure the tube is stable you can paint them with a variety of products. Some are more of a dye and will just change color others will add a thin protective barrier to the tube.


I get a lot of my supplies from:

I got all my hypalon fabric and glue from NRS as well.

The hypalon material is 3 layers: an inner layer of neoprene to provide airtightness; a layer of fabric to provide dimensional strength; and a layer of hypalon to provide UV and chemical resistance. If the outer hypalon layer degrades, it often begins checking (cracking like an alligator-skin pattern), which allows water between the 2 rubber layer. Then the fabric starts to go and everything comes apart, which is generally considered bad.

If the hypalon layer is sound, I doubt that the paint is going to do a whole lot other than make it look a homogenous color. I just don't think the paint is tough enough (at least the ones I've seen), though I admit limited experience with it. Someone with more experience with painted tubes may have better input.

Thank everyone for the feedback! I really appreciate your help. I will work on the patches first - replace old patches, add larger wear patches in an offset color, then replace the rub rail, then paint.

Which specific paint do you recommend Ryan (or anyone with experience) for tubes like mine that could use a protective layer? I had originally thought about Tuff Coat, but it sounds like there may be other paints that are more suitable.

Thanks again,

John
