Actually it does heed advice and makes sense.
If not repaired properly and even if properly..repairing blisters opens up further edges of resin starved mat ( This is 99% the problem) for water osmosis to have access to at a future date.
I have blisters on my boat...I have repaired a couple but the tiney ones I just leave...All of them are in the reason starved mat used as a print through barrier for the gel coat fairness....The underlining roving and cloth is a translucent green and very shiny indication a stellar layup.
It is this cross section that is the culprit 99 % of the time...I could personally care less if that cross section of the hull bottom fell completely off my boat in one huge shed like a snake skin....Actually I would prefer that.as pealing a hull damages the roving in the process...Id take the opportunity to lay up another payer of roving and fair it with thickened epoxy for a much stronger hull cross section better suited for my needs.
Here is a picture of two I repaired....I didn't even bother fairing them back flush with the hull....Its an experiment to see what happens now at the edged of the repair..
I exposed back to solid mat ( as solid as there is ) and applied 2 coats of epoxy over the exposed roving as a barrier coat...slapped on two coats of bottom paint and called it good....If after a couple years in the water more do not appear around the edges I will fair them.
They were two of the three biggest blisters on my boat at 1/2 dollar size...all the other are nickel size of smaller....they are about 3 or 4"each now to get back to good mat.
CSM has little if any structural function on our boats ...it is used as a filler and or like i said a fairing layer nothing more...I have personally yet to see roving on any boat affected with blisters...saying roving NEEDS CSM for blister protection is just plain heresy.
There are many old boats that have roving as their only skin with a faring compound used to hide the roving s pattern...These boats seldom if ever incur any blisters of any kind.
"Go Simple...Go Large"
Relationships are everything to me..everything else in life are just tools to enhance them.
The purchase price of a boat is just the admittance fee to the dance...you still have to spend money on the girl...so court one with something going for her with pleasing and desirable character traits others desire as well... or you could find yourself in a disillusioned relationship contemplating an expensive divorce.
