Hoping for some advice- I applied flex coat (heavy) to wraps on a rod I am building. Although I was cautious to keep the mixture in a 1:1 ratio, when I checked it this morning the coat was still sticky- I wonder if the flex coat was too old.
Anyway, can someone advise whether or not I can merely apply a new coat over the sticky layer and hope for better results or whether I should strip off the old layer and start anew...
Thanks,
John

I have found the best way to apply finish is in a low humidity area (a dehumidifier helps). Also I make sure that there is fan going 4 hours after I applied the Flex Coat, make sure your area is clean (you don't want any dust or debris inbeded on your finish).

John--before applying flexcoat let the bottles stand in some hot water a few minutes and also try to work in a room above 70 degrees. The warming bath will make the flexcoat thinner and it will saturate threads better and have fewer bubbles. Keeping it warm will allow it to set up faster too. If your current project is still tacky after a few days you may need to add a thin top coat to seal it and finish it--FlyDoctor

Flex Coat will not "age out". It will still set up properly 100 years from now. You'll want to apply a very thin layer over the top of what you have now. The mention of slightly warming the bottles to make the mixture a hair more managable is a good one.

Do make sure you get an exact 50:50 mix. Syringes are the best way to do this and don't scrimp on the amount you mix. A small error in small mix can be enough to foil the cure. A small error in a large mix might still be contained in whatever margin for error exists. It's cheaper to mix a larger batch and get it right on the first go around than mixing a small batch that has to be repaired or replaced with another.

John,
I also use FlexCoat heavy and I'm almost sure your problem is due to you didn't mix long and well enough. I usually mix 2cc-3cc fr. each part for 3min. When you think you have mixed it well, mix another 30sec :). I have your problem on and off the first year, none the last 2 years. Should not be tacky after 6hours, good luck.
NSH.

Thanks for all of the suggestions. I believe the rod will turn out nicely, and my girlfriend will love it!
