Ocassionaly I have a problem with the finish creeping up the guides. I have the most problems with small guides (size 7, 8 10). Do I need to apply less finish and mulitple coats?
Any guidance is greatly appreciated

It sounds to me that you might be using to much finish at once. When I use a high build I apply enough to let it soak into the wrap then I apply a tad bit of heat to get it to penetrate better. I then go back over it to get it even and a nice roundness to it.

Do you mean the finish gets oval instead of flat on the wraps and pulls away from the end of the wraps?

I'd like to hear what you think causes that Bobbin. I think Green is referring to finish crawling up the guide legs

Where did he go? I re-read his question, guess I mis-read it at first.
The finish getting barrel shaped is just a liquid wanting to be in the shape of a drop while it can still flow good. I think that is why some builders cover their wraps with the dryer motor off for a bit, or else turn it off when all the wraps are covered. They use a little too much on purpose and let the extra collect on the bottom. Then they swipe off the extra and turn the dryer motor back on. Some use a flat stainless spatula to apply the epoxy instead of a brush. They say they get a flatter finish that way. Everyone probably has a way they like to do it.
When I use a brush and apply a little too much it wants to form a drop / bulge around the middle.
Not sure about creeping up the guide legs.

What do you think, Stickfish?

only time I've heard anyone talk about going up the guide legs was lite build and too much finish and too many RPM's. Finish does like to act like water and form a meniscus - I just go back an hour later and check. If its turning into an oval a little heat and spread it back out does the trick with high build - but I would not use that technique with flexcoat it will burn and bubble if it gets too hot.

I do like Bobbin say's. I flood the finish on, get everything covered real well then turn the dryer off with the guides all facing up. The excess finish will sag and drip off, or I can take a card and carefully scrape it off the bottom of the wraps.
It works the best for me, leaving a good flat finish and total coverage.

Sorry, been gone for a while.
Yes, the finish creeps up the guide legs and in severe cases fills in the space between the guide legs.
I tend to have this issue with smaller 2-foot guides (size 7 or 8)

How fast are you turning it on your dryer? My dryer only turns at 4 rpm, works fine.

I think that it is difficult to prevent this especially on the smaller guides. I have the most trouble with this occuring on the #6 v frame guides especially if I am trying to get by with only one coat of epoxy. It is not normally a problem if I have a little more patience and use two lighter coats.
The way that I deal with it is to wait until the epoxy has just started to get a little thicker and then sharpen up the end of a wooden tooth pick and insert it in between the guide feet where the epoxy has wicked up. The epoxy will stick to the tooth pick so that you can remove the excess. Sometimes if I have waited a little too long and the epoxy is thicker I will hit it breafly with a Bubble Buster to heat it and make it thinner.
