Top joint wraps have been drying for 48 hours. 7 out of 10 wraps have dried perfectly but spots on three wraps are tacky. All were done from the same batch. Any reason for this? Thanks.

If your epoxy was applied from the mixing cup it is possible the the uncured was taken from the side of the cup and was not mixed as well as the rest of the epoxy.

No, I pour it on to foil, i mix it for 2 1/2 minutes and make more than enough of it. On the three wraps that have a problem it isn't the whole wrap, just an area that is about a 1/4 inch square.

Try mixing it in the cup for the same amount of time, then pouring it out onto the foil, Mark. I think that you'll get a better mixing of the 2 parts in a cup than on foil. Worth a try; it really sounds like a problem associated with not getting everything mixed up real well to me...

And you can put another coat over the wraps and they should be fine.

This little trick I use has saved my donkey more than once on wraps with that fish-eye, gap out, or blotch off. It's best practised on a tramp rod first, a couple of times before trying it on a client rod, or your own.
Also, you need to know your resin on a first name basis, as they all have different pot lives, and characteristics during their pot life and set time.
Mix 1/2 - 1CC * of the resin to start, more as you become good at the trick, and can handle more than one guide at a time. OK, the trick: permit the resin to **nearly** set, so you have to literally **drag** it over the wrap, it's that stiff. Wait too long, and the resin will ball up, and not drag. Wait too soon, and the resin will simply fall away from the void you are trying to cover. Wait just right, and the resin will begin to set so it cannot sluff away from the flaw.
After a while, you can get right to the edge of the envelope, and salvage your repair resin with a bit of heat from the hair dryer. Remember I mentioned you need to know your resin. some formulations will simply harden like a rock with this heat hit, while others will get to the consistancy of volcanic lava...just barely flowing. Take away the heat, and the resin cinches up.
Works for me.... your mileage may vary.
