If it were my boat, I would swap it out if at all possible. The closest thing I have seen to that problem, is a hypalon boat starting a delamination, it began in one spot, and just got worse, till the company sold it for a very low price, saw it a few years later, in way worse shape, new owner still happy though, cause he got it dirt cheap.
It is possible it is less of a concern, but I would not want to chance it myself. Certainly call RMR, see what they say.
Best of luck!
We can't always agree, but we can still be civil to each other.
