Andrew, here's what we use and it works a treat. Either get from somebody or
drink your self to get some 1/2 and 1 liter soda bottles. Then, go to Wal-Mart
or
other store of that type and find the screw on pop-tops like the ones on a syrup
bottle. Clean out the inside of the bottle well, and you're set. We use the
1/2
liter for hardener and 1 liter for resin. It makes it VERY easy to dispense
very
small, accurate amounts with our digital scale. Keep a paper towel handy to
wipe
up drips.
The hardner does harden the plastic bottle over time, leading to leaks, but we
just replace it every month or two. We've found no affect on the cured mixture
---From the plastic. It can't be any worse than those resin pumps with the
plastic
lines. We keep a bit of each batch leftover and give it the "scratch test", and
we've always had excellent results, even if the workshop is in the mid 50's (F).
We use heatlamps to locally heat the layups rather than trying to keep the
entire
basement warm, but the leftover resin can be sitting on the bench away from any
of
the heat.
