I agree with William on using underlay - perhaps we can get here is better
quality. I also spend time - with permission from the lumber yard - to pick
through the pile and get the best sheets. There's a lot of crappy product
out there especially if you buy from the bigger chains.

I currently have 4 small boats - all built with underlay, including a
MiniCup sealed with anything from 3 coats of epoxy and fiberglassed chines
on the MiniCup to polyester resin, to just paint. The only problem I've had
is with the skiff that was just painted - a bit of delamination that was
quickly fixed with auto-body filler 3 years ago and it's still holding up
well.

It is true that you get what you pay for but the ratio of $$ to fun I find
pretty high using the lower end materials.

I am very sorry I used bathroom underlayment for my two MiniCups. It
is such poor quality material that now I am covering the boats with
fiberglass. I highly reccomend that builders use a higher quality
material.


That's why I get so ****ed when I see William teling everyone who will
listen that cheap **** material is worth using... Sorry you had to
learn the hard way. Personally I think his ill advice has probably done
more damage to builders and their projects than the dreaded Dutch
honeycomb builder...

Use what meets your requriement. I've got good value and much enjoyment
out of the boats I've made from lauan underlayment. I've used but don't
recommend virola underlayment unless you can tolerate a high degreee of
maintenance for the lighter weight and tighter bending radius.

Design (scantlings) and workmanship matter as much as materials for
durability.
