Epoxy for those pinholes...

[Jenna Antonelli]

Hello there! I've been lurking here for a week, eating up all the tips and tricks I can. So thank you all for that! Now im an official member and can't wait to talk shop with everyone :) 

Now, I have a resin toy in the works and im currently pulling some great casts but I will of course have pin holes and little spots to fill with epoxy and sand...Do you guys have a specific brand or type of epoxy that works best for a smooth seamless fill that sands nicely? I have a few kinds already, Loctite putty you mix with your fingers, a two part liquid kind... I dont want to just start throwing things on and see what happens..if I can help it ;P

Thanks in advance!

What I've found that works good is either zap-a-gap or using milliput 2 pt epoxy, thinning it down with alcohol so it's a liquid and brushing it on than sanding it down.  You can also use a cheap, fast setting glue.  Also this site has a lot of info about building resin garage kits, and he just used a surfacer to cover pinholes.

Thanks! I wouldnt have thought of thinning it down so I will try that out for sure. I actually tested out the two part liquid epoxy..not a fan. Its a 5 min setup and 24 hrs later its still tacky... Im much more comfortable with epoxy putty. I've also read about using hot glue and baking soda. 

Thanks again for the links! Im going to try each method and pick my favorite. I DO love the trial and error process :)

If you add a little fast drying superglue to the 2 part liquid epoxy it will speed up dry time.  The milliput dries in about 15-20 minutes, and even faster if you heat it.

Also you can buy an epoxy accelerator, but the superglue has always taken care of that for me.
