I find that acriglass is too thin for some applications, but it cures to be very hand and really attaches to the wood. The acriglass gel does not run, but it seems to not get as hard when dry. I personally like mixing in a little bit of the regular acriglass in with the gel for a good compromise.
I have also used the Pro Bed stuff that Midway sells. I liked that for a one with a paste consistency.
