'You know that my day job is working on boats - Right?'

REPLY:  No. Actually i had no idea. But youre obviously the man with the
info on this subject.

'Bubbles like that are typically where the laminate (chop) did not
adhere to the gelcoat. Do you know how this is done? They spray the
gelcoat in the mold first then put the composite inside the color coat.
The composite (laminate/fiberglass) is actually sprayed also by a nifty
thing called a chop gun. It mixes the resin and catalyst (hardener)
right in the gun and draws in a yarn of glass fiber that gets cut into
small pieces as it is coated with mix at fired at the mold. Gelcoat is
also often sprayed with a mixing gun but with that gun doesn't add yarn.
Now the problem. All this stuff works great when it works, but it
doesn't take much to make it not work.
A couple of drops of water falling on the color coat prior to laying on
the glass will cause just such a problem, and cutting them and pushing
the bubble down will do little good. Failure of either mixing gun would
cause that problem over a much larger area.'

REPLY:  I appreciate you sharing this with me. I have a deeper
appreciation for how its done now.

'Now the answer you were really waiting for. To repair this correctly,
the blistered gelcoat has to be removed the exposed surfaces cleaned and
new gelcoat filled in. Around here, if that is all that need doing, I
would expect to pay 60~100$ (depending on the actual area) for this job.
If you are in the Lake Villa by Waukegan, that should be about right. '

REPLY:  Well, based on me getting this RV for well under the NADA RV
Price Guide,  $100 is a welcomed expenditure to have it repaired right.
Yes, im in Lake Villa near Waukegan, Illinois .... does that mean you
are in my area also ?  If so,  when i pick up this RV , would you be
interested in repairing it correctly for me ? If not, then i might go to
the Auto Body Shop at the bottom of my street since i know he works on
Corvettes which are fiberglass also.  But, my first choice is yourself.
