Re: Osmosis conspiracy theory
good point jimgo
here is my final take for the op
1. how deep and what is your hull construction?
2. if cored you are in more danger than if solid, yes even if it was crappy and overly layed up glass and excessive resin back in the 60s and early 70s...they do fair better since they are so thick.
3. are the bubbles in the gelcoat(extrenal layer) or are they deeper than say 1mm skin
if the later its more of an issue but still liveable with and fixeable.
if the former I dont even bother
I have had 3 or so boats with minor blistering...most blisters were in the dime size or rubber pencil tip size or slightly smaller I had some with about a dolar pancake size and what I simply did was scrape off the gelcoat or bubble and apply some nice mix of thickened resin, sand and then off to the bottom paint
simple and it lasts btw...if next haulout more pop up which normally happens just do the same...
if you do want to eliminate all SURFACE pox you can barrier coat...simple but so expensive these days and not worth it for the majority if used boats out there especially in the median cruiser size range...30-35feet
its unfortunate we are in the dinosaur days of yards letting you do your work, cause I beleive this has become more of an INFLUENCER of potential buyer turning down otherwise simple bottom jobs on potential boats they are looking at.
last place I worked on a boat was gravelles in california, and apparently they no longer let you do any bottom work which is a shame...
I did a nice bottom job, strut realignment with new cutlass bearing and engine realignment...in a a week.
I did just this last year...
in any case blistering or osmosis threads, like oil type threads or inboard or outboard threads always seem to be extremist and get off track very easily and bring out very high and mighty opinions both good and bad.
so lets all be happy
Merit 25 sold...Islander 36 still afloat? who knows...Im still in Columbus, and back...I think...jajajaja!!!!
