Grip reduction epoxies

[ruchik]

I've just about had it with Devcon plastic welder. Although excellent when it's hardened, the stuff is so thick that it does not flow, and I have a helluva time trying to fill any gaps with it. Are there any other freer-flowing epoxies people can recommend when doing a grip reduction?

I've always used Brownell's Acraglass with great results.
