repairing hypalon scuffs

I have a 2005 NRS cat about a dozen small scuffs in the thin outer layer of the hypalon, so that the fabric is showing. Biggest is the size of a quarter. These are in places where frame/cargo has rubbed for awhile, or where I've parked it poorly and it's rubbed on rocks overnight. Most of them don't leak, but I don't want them getting worse or being a weak point. I've used aqua seal before, and this works fine for a year or two. I called NRS and they recommend using a hypalon patch, but this seems like a lot of work. Is there a better way to repair these?

Prophylactic patch is the way to go. It isn't really that hard - the instructions that you get typically make it sound harder than it really is. Especially when there is no "hole" to patch.

Patch them scuffs if you see fabric; they will not get any better, only worse.

And patches are a sign of a veteran boater; like scars on a warrior

Urethane

I have found that putting a urethane coating on scuff marks like that is the best way to go. I have put System 6 in the places on my raft that get the most abuse and they have held up better than patches or chaffing strips, both on the top and the bottom of the boat. The only down side to this product is that it has a long cure time (10 days without accel. and 5 days with the accel.) However the areas that I have covered with the System 6 look like the day that I put the product on 5 years ago. Let me know if you want anymore details about the product.

I Like It!
I loaned my boat last year, Made the left run at Bedrock myself this year. Either of these events left about the same number of scars. My boat is only 16 years old, I think this winter I am gonna slap on a little extra rubber. Easier in a nice snug garage before she blows than on a nice sunny beach after.

The NRS cats have a black wear patch on top of the hypalon on the topside of the tubes. I also have scuffs there but have decided to not worry about them until I start to see the fabric fray. Reconfiguring my frame periodically has meant the same areas aren't getting rubbed like they used to. I'm also more careful trailering it and try not to load too much into the frame when I do. The black on the bottom of the tubes is NOT a wear patch and will begin to leak. I have applied patches to those areas and am more careful about parking on rocks.
