    Hi, what is the optimal time you've found to work the Flexcoat around the guides?

    Do you let it set up a few minutes or start applying right away?

    At what point does it become too thick to work?

    I'm mixing between 70-80 degrees ambient temp.
    My dryer is 9 RPM.
    I'm using the supplies paint brushes.

    It's runny for about the first 4-5 guides, then gets thick and hard to apply for last 4 guides.

    However, I can see how the thick consistency could be desired because it lays down a thick coating.

    It's just that window doesn't last very long - should I have to mix two batches to do 9 guides or am I missing something?

    One thing I missed on this rod (my initial coating of the threads) is pouring the mixed Flex Coat out on aluminum foil, I guess that would have increased my optimal working time. But my using it from the plastic mixing cup was to paint a fast thin primer coat (it just got thick unexpectedly fast)...

    I have used a ton of Flexcoat. You just need to learn to work more quickly. You should have no problem doing 9 guides from a single batch. Once the Flexcoat is mixed start applying it immediately. You should be able to do a single guide in 10 or 12 seconds and the complete rod should not take more than 2 minutes. I have tried all of the tricks of pouring it out on aluminum foil, the bottom of a coke can etc but I get excellent results straight from the plastic mixing cup. Apply it quickly, hit each wrap very briefly with a propane torch as you rotate the rod then let it set for 30 or 45 seconds with the guides pointing up. All of the excess epoxy will sag to the bottom of the wrap and make a quick pass with your brush to remove the excess. Put the rod on your dryer and after a few minutes check for any bubbles that may have formed late. I have dryers from 3 rpm to 12 rpm and they all give the same final result. I have done hundreds of rods this way with excellent results. Other people have their own special tricks but this is what works for me.

    I just redid 2 rods, one 8', one 9', mixed one cup of flexcoat in the small mixing cups, did all the guides on both rods before it started to thicken. I'm in my mancave, temp in the mid-hi 60's....You'll get faster with practice......

    I've never seen Flex coat setup fast enough to not get 10 or more guides coated,even when it's a 100* degrees out in the garage.And i'm in no hurry to coat them.I mix thoroughly,let it sit for a few minutes,mix again and coat guides.

    Everybody applies finish differently, so you'll need to take all this advice and figure out for yourself what works for you.

    I apply by hand to a rod I'm rotating by hand with a brush and I've found 15 minutes to be a "normal" working time before the chemical hardening makes the finish too viscus for my liking. I generally do 4 or 5 coats on a rod and apply thin coats of finish to every thread layer, because I hate bubbles and the more the finish thickens the harder it is for the bubbles to escape (even with flaming).

    There's no law that says you have to mix enough finish to complete the project from one batch. I usually mix two small batches (2 ml of each) to do a rod. I'm very experienced and know how much I can use in the time before it starts thickening.

    I mix it in the cup and apply from the cup too, bubbles and all, because the bubbles burst easily as long as the finish is fresh when flamed. OH, you don't need much heat either.

    You also might not had an exact 50/50 mixture of the resin and hardener.

    These are especially useful tips to me, I have a problem with very small bubbles and buildup inside the top where it is hard to get at (it sort of looks like the Milky Way in there, been hitting it with a hair dryer) - I can't hardly wait to start my second rod now to use your new tricks ... thank you.

    The experience on everyone's workflows, especially time windows, are helping me figure out my approach - much easier than trying to figure it out on my own.

    if it's too hot mix the flex coat , put it in the fridge{covered}, and cool it down. 80's is too hot and making it kick off faster. start with the small guides first , it takes less time to coat them , and less set up time for the finish. if the finish starts to setup , you can use a hair drier to get it flowing , but it will be hard to do.

    if it sets up that quick your mix is off (not 50/50) or you are slower than slow......

    I never rush when applying finish if it starts to become unworkable I mix another batch.

    I think flex coat is the slowest setting up. Ton a ton of rods and never had it setup doing 2 at a time. I use a heat gun with 18rpm motors. I can get it pretty hot and it won't drip off going that fast. I mix the shit out of it and the bubbles come out easy when it's hot. I use heat 3-4 times when it's in the dryer.
    Lots of ways to do it, just keep at it until you find one that works for you.

    Saltydawg (Bill) does some great videos on here by the way

    Mr. Saltydawg uses a 200 RPM motors with a clutch and wide brushes at least in this SaltyDawg rod building video putting finish on a rod.

    (We are apple & oranges apart in approach with my 8RMP and tiny brush and no clutch ... that's why I didn't post it earlier).



    In review, Mr. Saltydawg does discuss his approach to getting the finish on the guides in depth ... could use some extreme close ups of his detail working, imho, but great info, professional rod building tips & tricks overall.

    Wish decades of experience could be put into a paragraph or two of text.

    The problem with experience is there's only one way to get it.
