When applying the gloss pva release agent it always drys with tiny air bubbles in which are raised up and show up in the new mould, then I'm forever sanding the new mould. 

Iv tried using a foam bush, iv tried wiping on with tissue, and iv tried using a small air spray gun that attaches to a little air canister. But I found when spraying the pva on it sometimes beaded which wad also no good.

Hope you can help. 

Cheers
