Hi, I am thinking of using some of your tooling gelcoat to make a mould off a part.  Does anyone know what kind of time (min and max) I need to wait between applying the first coat, and applying the second and then applying the layup?  I belive you cannot leave the gelcoat too long between coats as then the next layer will not adhere to it correctly.  Also can this gelcoat be used at 15 or 20 degrees c insted of 25 (I understand cure times will be longer)?

Aother question I have regarding this gelcoat is can it be used as a topcoat, I.E. applied over a layup and then sanded when cured?

Many thanks, lee.
