I am repairing a rudder on a 27 foot sail boat and have applied interprotect 2000 over the new glass repair.....I have mixed and prepared the product as instructed and waited  the necessary time between coats [4]  The product went on easily  and looks good......it is not tacky , sticky or saggy , but it is soft......ie:  I can put my finger nail in it .

This is after 3 d...in a heated building @ 55 deg F with @ 50 % humidity ......Should I give this more time to
"cure".............or remove it and start again.

Thanks ...Steve.

Assuming your mix ratio is right (3:1), assuming you mixed thoroughly, assuming you gave the mixed material about 30 minutes in the pot to induct before applying and assuming if you thinned the material you used the proper thinner (2316N) then . . .

I would suggest applying some localized heat to the rudder, get it to 80°F or so for 4-5 hours.  This will finish off the reaction and you may also have some solvent entrapment that needs to vape out.  After allowing it to normalize to ambient temp wipe the rudder down with an ammonia/water solution then evaluate.

You likely have enough epoxy on there now.  I'd give it a thorough light sanding and apply your bottom paint.
