  • Foam Tac Thinner?

    I have a bottle of Foam Tac that is 80% full, but it's gotten thick and basically unusable. How can I thin this down and still have it be foam safe?
    I hate that motorcycle they make me ride. I'm here to tell you, there ain't nothing in the world I hate more than that elephant under my ass.

    Heat...get a bowl of hot water to leave it in while you're using it.

        What I do with my 2 ounce bottle is when I'm done using it I take the dispenser cap off and squeeze the bottle to get most of the air out and put the cap back on (assuming you hadn't tossed it) and it stay good to the last use. R

          This issue that FLTRI points to is exactly the reason I requested(Oct 2016) that Motion get the 2 - 1oz tube pack for the same price as the 2oz bottle.
          Squeeze out what you need and recap, no air in tube like there is in the bottle as it gets emptied to start the hardening process.
          Must be ordered quite a bit because this is the second time I've seen it out of stock.

            I went the same route and got the tubes . I've used all of one and am into the second one with no waste to speak of.

              OMG! FoamTac comes in tubes????? It's like "the best thing since sliced bread", but now it has no crust.
              For me, I'm not nearly as frugal as some folks. I use as much as I can out of a bottle and if the rest goes "bad", I chuck it and start a new bottle. This hobby is not exactly cheap to begin with. A 10 buck bottle of goo isn't going to break the bank.

                No, but it is annoying when you need some glue, and find out it has turned to Jello. Thanks for all the replies, I'll try the hot water trick. Any ideas on what to thin it with? Acetone, rubbing alcohol paint thinner, reducer???

                  I use both, I just use the 2 ounce when I need more fast.

                    Acetone eats most foam. Just check what you're using first to see if the foam will survive.

                      EPO will stand up to MEK, so acetone will not melt it. I believe that formaldehyde is the solvent for foam-tac. R.

                        If your Foam-Tac spoils then you're not doing enough repairs, which means you're not crashing enough, which means you're not flying enough...get with it guys

                          Some of us gave up crashing for Lent and never went back.
                          :p

                          Actually, I rarely damage the models from crashing without having something break in flight, causing loss of control now. Hangar rash is my worst enemy. You don't use much foam tack for that.

                            Oh, just a reminder, Foam-Tac is great for anchoring grub screws. The pesky landing gear upgrade on the Tigercat let go on me while still in the basement thank God, so I pulled the whole thing apart and Foam-Tac'd the strut to the retract pin and Foam-Tac'd the grub screws into the strut itself, now let's see the danged thing come off

                                  Push limits with plenty of altitude... find what it can do... then do it lower.

                                    You don't fly through FPV gates, obstacles and tunnels through the woods at high altitude.

                                      Beacon Glue company maker of foam Tac recommends mineral spirits for clean up and thinning.
