Default Flex Coat questions

I put a coat of flex coat on the new rod last night. I made a full 6cc mix and got half way down the rod when it began to get too stiff to keep using. I was surprised at the quick pot life, but honestly I don't know how long it had been. I was down to 2.5 cc of each part and mixed it up and just got to the tip top before it was to sticky to use.

I can't find a pot life on any of Flex Coats materials.

This morning, 6 hours later, everything was set nicely but still tacky. I am curious what the full cure time is? I have to go back and trim a funky thread fray, probably try to remove some dust and build up a couple guide feet wraps that absorbed the epoxy. Can I go over the epoxy if it is tacky or best to wait? I want to use the Lite.

thanks,

Better to wait until dry. As far as using 'lite' over the top of the regular mix....I don't know, but I'm not sure I would.

The potlife of a batch is somewhat variable dependent on room temp, humidity, and evenness of your mix. Once it starts to thicken I'm done with it and will mix more if needed.
They say if you pour your mix on to a piece of foil that it will give you a little more working time.

Dan has probably answered your question already, but if he hasn't, if you mix up another batch, put it on lightly and it'll kick the first coat.

Did you use the epoxy accidentally? The wrapping finish should stay in a gel state for plenty of time to finish a rod up without it hardening when mixed properly.

No offense to FlexCoat but I am not a fan. I used to have some Crystal Coat that you could mix up one-handed, drunk, blind-folded in a dark closet and it would always dry correctly. I have had too many issues with FC remaining tacky to use it anymore. I just use varnish for everything now. If someone can tell me the trick to making it dry correctly please let me know.

So you can put 'lite' over the regular?
I've only used one or the other, so I really don't know.

Thanks everyone. I should apologize for my unclear post. The epoxy is fine, it was tacky this morning, after 6 hours - but cured by this evening. I was jumping the gun with worrying about a sticky finish as it has happened to me before.

I mentioned the pot life issue as an aside.

My question was about using the lite finish. I did talk to Dan, (thanks Dan) and he gave some good advice about getting a second coat on within 24 hours.

I did trim a couple stray threads and smooth some dust spots and apply a second light coat.

All is good, so the rod turns.

Thanks again!

A lot of rod builders use acetone to thin out thread epoxy. Lite is just the same as regular build epoxy just thinner. I doubt they use acetone, but I'll venture to guess it's the same formula (as regular build) with a little thinner of their choice in the resin, while the hardner looks to be the same viscosity as the regular build. I don't use FC or FC Lite, but if I use epoxy, it's Threadmaster, and recently TM Lite. I still use spar varnish too. Love that smell.

I've always assumed that varnish was only for cane rods and silk wraps. Do you use it on graphite blanks and thread wraps? I am familiar with spar varnish, I used to paint for a living and do love the finish.
