I have a some colour matched gel coat (a every good match) that is non air hardening. I have been told that I can use it in as air drying if I add wax or someother similar product. I would welcome any ideas on this issue.
Gel coat question.

It is truly non-air dry you will need to cover it with wax paper or some other air inhibiting cover. This is the only way to get it to dry. For all repairs that are made after the boat is built we are better off using an air dry gelcoat that is color matched. All you have to do at that point is add the hardner and spread it on and wait for it to dry.

P.V.A. spray is the way to go
I believe you can buy this at auto supply stores. it is a spray on coating that seals out air. I's water soluable so, when your done you can wash it off. It's quite inexpensive.

wax agent
You are correct Colin. Matched gel coat is the best way to go to achieve a good blend. Any marine store will have a liquid wax additive which can be added to eliminate the air. The way it works is once added, it will rise to the surface of the gel and create an air barrier which can be wiped off after hardening. An added benefit it that it enhances the gloss surface you want to obtain. Don

Sellotape!
For small repairs I just stick Sellotape over the liquid gel. It keeps the air out and helps to stop it sagging on vertical surfaces. I like the idea of PVA spray on release agent, though the link does not say it is for use on top of the gel, but on the mould where there will be no air anyway. Anyone tried this stuff please?
