Assuming this is the new caring, sharing, Harry asking I'll not take offense in
any manner so answer as best I can.
Me personally with my own delicate hands???? None.
I've seen & been involved in many including numerous using Mr. Vaitses's
methods. Why don't you get the book Harry & have a read you might even learn
something (well OK; that's probably a tad optimistic). My comments about glass not
sticking to timber are consistent with his comments. You would love the
introduction, it even mentions the covering coming off........ wait Harry ..........
wait............. one of your hallowed Rybovich sport fisherman. He feels that job
was well done, the best epoxy etc but alas after only 12 years it came off.
Here ya go may I quote him???;
"It was a good job of its type to have lasted so long, but one day half of the
bottom covering on one side fell off. Obviously, the epoxy had had a good grip on
the planking, since almost every square inch of the fiberglass took some of the
mahogany with it. A grainy, chunky veneer came away, leaving the boat's bottom
striated & pitted, as though she had been dragged over a bed of spikes a hundred
yards long. That the epoxy never did let go of the wood indicates an excellent bond:
it is important to an understanding of fiberglass covering to note that it was not
the glue but the wood that came apart."
end quote from his book. (gees Louise I had to look "striated" up; d'oh me ;-))
This bloke has had to endure prejudice that might even beat you & your OMC
dealer mates in this NG, but he's persevered & now has a well respected fibreglass
over timber system that actually works in the longer term.
Unlike some marketing scams he just gives out the info, doesn't start marketing
his special secret formula resins & staples, I say a real good bloke.
Very, very much abridged, paraphrased etc Harry it goes a bit like this; if the
timber is soft naturally & absorbent or alternatively so far gone, that resin can
actually soak into the material then it will fail by delaminating the timber
(clearly if it's that porous it's got no shear strength) OR if the timber is
stronger, new or in good condition then it's own construction, oils etc will
resist/prevent the resins actually getting into the material so it'll fail at or
very close to the surface junction (as soon as the resin has cured that's it, never
goes any further & as the un-***d timber below changes/moves so the joint
fails; maybe the Rybovich??).
Whereas his methods allow any adhesion that is there to still be used yes, but
equally with the mechanical fastenings backing it up. We have used stainless staples
in the past with great success & if a similar job comes along, will again.
Thanks for your non abusive genuine interest & enjoy the book it's really good, lots
of pics for people like you!!
