Vinyl-ester in the promated state as you would buy it from Wicks or A/C Spruce
has an advertised shelf life of three months. I have stretched that to six
months by keeping it in a refrigerator; your results may vary. Vinyl-ester
resin puts out lots of styrene fumes when you add the catalyst - good way to
turn your workshop/garage/house into a gas chamber. MEKP is the catalyst
commonly used. This stuff looks like clear water, but will work like
concentrated sulfuric acid if you get it in your eyes. The literature says
"blindness in 4 seconds". (Who that was tested on is not stated.)
A fresh air breathing system is definitely recommended, along with eye and skin
protection.
On the plus side: it's about half the price of epoxy, works the same, has about
the same cured strength, but has been formulated to be gasoline proof for auto
gas, 100 LL, gasohol, etc.

And buy vinyl-ester only when you are ready to use it. It has a relative
short shelf life.
And only if you have to use it. It is not for normal consumption.
Research
it well first.
