newo - that is something else -- pic's are worth 1000+ words...

I like playing and building and fiddling.... So if U R of the same mind set - all the yep - go for it tips R good.
I would follow richswing's suggestion and peel the lot. U might have water damage under one of Ur fins anyway (where it is black).
I have defaulted on using epoxy (kinetix 104h 125h - not thru' specialist knowledge but recommended at glass shop and has lasted 1+ years as I gradually use it up) - Last job I did a flood coat and easy as - pulled the masking tape off after approx 2 hours well before fully cured - I find less hassle cleaning up / and sanding edges. Might consider 2 layers of glass -lighter weave of cloth and decent sand between 1st & 2nd.. the layering really adds strength (but at a weight penalty - hence the sanding)..
Cost - well I invested in the resin (>$200 from memory) as I had paddle boards (epoxy based - nippers equipment (newbie volunteer


) & dodgey surf boards to fix and both my boys now patch / fix as well. The rest is fairly cheap. The standard resin (polyester?? not epoxy) was cheaper - but more toxic and the mix with the hardner I had was fiddly for small jobs as the ratio was 5 to 1 and in humid conditions was not so easy to use when starting 101 glassing


+ the hardner had a short shelf life - i.e. good for constant production but not for irregular repairs.
I also did a bulk buy of SOLAREZ from the importer ($12 / tube) - this stuff used well is great for small quick patches (have this and repair bog in the car


) - retailed at $24 -38


.
If U go for it would like to see the pics...
Suppose U must have ridden board back to shore like that - hoping it would not break..
Cheers
