Gel coat issues with easy-lease for fibreglass wet lay up

Hi, I have recently purchased some of your chemical release agent and am having some issues getting the gel coat to lie in the mould properly. It appears to be repelling in areas and I am having to keep rebrushing to ensure complete coverage.
In it's self this is not an issue, however I am concerned this reworking of the gel coat is causing the 'alligatoring' issues I am experiencing.

I have followed the product instructions, used the mould cleaner, and applied 4 coats of easy-lease 24 hours prior to lay-up.

Have you any suggestion as to what I may be doing wrong please?

Many thanks, Tony

The wax is lightly buffed as normal.

For reapplication the Easylease is loaded in solvants anyway which will dissolve most waxes.  It all depends how clean your mould is.  The wax will come off dead easy in a couple of mould releases, however for less aggressive processes like wetlay, the Easylease can last many releases before it wears off.
