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

Hmm. The epoxy gelcoats that I use HAVE to be reinforced during the tacky stage, if you let it dry nothing will bond to it and it needs to be scraped off the mould. I Iran get away with it with my polyester gelcoats, but not the epoxies. But I use Airtech stuff, the EC stuff may be more forgiving?
