Hello all, Ive been considering buying some LocTite epoxy putty for a cheap alternative to greenstuff. I know its only a couple bucks cheaper but my only source of greenstuff is over 2 hours away, or +6$ through the mail. I have heard it is not good for sculpting but I was mainly just going to use it as a gap filler. If anyone has any thing they would like to share It would be greatly appreciated if you would do so.

I have used 2-part epoxy putty. It works & strong, but because it's harder than most plastics sanding can have bad results. The plastic around the gap you filled will be worn away before the filler. I learned a trick when I was building lots of plastic model airplanes. Alot of those kits have a gap between the wing root & fuselage. What I do to fill gaps is mix up a slurry of Elmers glue, baby powder, & a little water. The exact mixture you'll have to play with to get the consistancy you want. The good thing is everything cleans up with water & almost no sanding.

I use Oatey Epoxy Putty (found in the plumbing dept) all of the time to great effect. It sets rock hard in under 10 minutes and is very easy to sand or file. It works wonderful as a gap filler. Just wad it in place, cut away excess while it's half set, sand smooth once fully set. I wouldn't use it for sculpting but I always have some on hand, there's always a use for it somewhere.

I would recommend that you try the Loctite product. It probably has slightly different characteristics than GS, but that isn't always a bad thing. The Oatey product I use sets faster and harder than GS which makes it much better for gap filling.

Thanks for all the replies everyone! I went ahead and bought some of the loctite stuff today and its not that bad, real short working time though, not set but still unworkable at about the 3minute mark. one other thing though, it doesn't adhere to plastic very well but it was a quick fix with a little drill bit.

You could try to scratch up the surface of the plastic first to give the putty something to grab on to. Alternately if it pops off you could superglue it back in place.
