Unless the surveyor siad they are structural or a safety issue, you won't get your money back out of doing the work. While there is a good feeling in having everything on the boat perfect, unless you have enough time or money to throw at it and not be stressed about it, don't worry about it.
Gonzo, would you like me to take a new profile picture for you?
There are other resale issues than getting ALL of your money back but when added together it may come closer than you imagine. I had to wrestle with these issues in making our decision to do a two layer peel.
First of all, many boat buyers will not even consider any boat that has blisters. So if you dont fix them now, eventually when it comes time to sell your older boat, you will be eliminating potential buyers.
Second, a potential buyer may show you genuine interest. But he will use the blister repair to knock down your sale price. He will ball park the job based upon a peel job and then lower his offer accordingly. Now you may have wished you had gone for the peel job years earlier.
Third, in the scenario above, peel jobs will not be cheaper. So the reduction in price may be higher than if you paid the cash now. Remember that fiberglass resin is a petroleum product, and as such, will change price proportionately to the commodities market for crude oil. Then add to that the sky rocketing cost of health care for employees, which translates into higher business operating costs. We will all see much higher increases since the govt has mandated health care and increasaed coverage for "ne'er do well" children who dont want to leave Mommie's home until age 26.
Fourth, I concluded that I dont like broken things. I fixed it and felt much better about it. My hull is now STRONGER than when it was originally manufactured. The 1808 Kyntex cloth (x2 layers) makes it extremely bullet proof. And last summer while cruising along the Chesapeake Bay in calm water, we hit something submerged against the hull with a THUD!!! loud enough to be heard clearly over the engine and stereo. Never saw it even though I went back to look.
So there are a lot of factors to consider. I think it comes down to pay me now or pay me later.
