Mould gel coat - it set before I could apply the putty

Hi,

I prepared and coated the original part with gel coat but got called away before getting to apply the putty at the tacky stage.  The gel coat has now gone hard.

Is there anything I can do to make the gel coat and putty now bond?

Thank you very much,

Nick

If its our green goo and putty then sand back like Matthieu said.  It can help to add another thin layer of epoxy gel or even epoxy laminating resin as a coupling coat. 

If it hasnt gone fully hard, just lost its tack, then you can normally get away with just another thin layer of epoxy as above.
