Drop the west system and go to System 3 epoxy.
Go to their website and read the specs.
Theirs is the best low temp and in my opinion is an overall better product
line. Mertons is priced well and has great service.

Read the system 3epoxy manual. Good reading even if you use another brand.
A plastic covered piece of cork covered plywood jacked up from the floor
works well for that kind of repair.
The over promoted west system of the vacuum bagging is not something I'd
try for that project.
Read everything you can on fiberglass repair.
If you must try the vacuum stuff save some cash and get the $10 venturi
valve from harbor freight.
The insane price of over $100 for the west system one is a joke. Try a
few lay ups on the bench and you'll see it's useless. Epoxy dries too slow
for a compressor type vacuum system on large work and the overall system is
not suited for large repairs anyway.
You'll find a nice peanut butter consistancy for the epoxy works well for
the first batch and is pretty much a must for the core replacement part.
If there is a chance for any small holes through the top deck without too
much trouble to fix it makes a world of difference in this type of repair.
I'v done several and it was a dream on the one where I was replacing the
handrail and not only for excretion,through bolts to help hold the bottom
form worked well.
Drop a line if you'd like to get further into this discussion.
