Answer 2

How do you mean unsaturated???

Polyester resin IS A LIQUID !!!!!

The benefits are inexpensive and easy to wotk with and not as toxic as some other resins like Epoxy. It cures fast and allows multiple layers of laminate layup over the coarse of a day.

Downside?  Not as waterproof over time as originally thought in the 70's...and now proven. It can be coated with Vinylester or Epoxy once it has cured to add water exclusion properties.

Vinylester and Epoxy are the prefered resins in todays boat market but they are harder for beginners to work with and more toxic.
