Good morning good people, We have recently been testing our Coro Model Fabrications skills and have come across an interesting altho fatal flaw in our technique! We bought 4mm Coro sheets to make a 'Start-Entry' for our sons year 12 final Ball, cut the pieces to shape, screwed up a number of pieces (something about mirroring front and back, left and right, blabla...) and then using Hot-Glue in your tradition lHot-glue gun to assemble the pieces. Easy-peezy-japaneeze! Or so we thought! Turns out, Christmas is in the hottest part of our summer, and by nature, Hot-glue melts thru heating Learning Right there!! Guess what happened to our fantastic looking Star- Entry!?!?! After returning the same way we came and picking up all the pieces and having run out of time, we figured that there must be a better way to do this! Hot-glue is NOT for our Christmas Coro items! Searching the forums (https://auschristmaslighting.com/threads/ungluing-hot-glue-gun-glue.8776/#post-78695; https://auschristmaslighting.com/threads/something-different.8739/#post-78232; https://auschristmaslighting.com/threads/pretend-coro-fabrication-instructions.3744/#post-32356 and https://auschristmaslighting.com/threads/where-do-people-get-there-hotglue-from.2599/#post-22774 to name a few) It was pointed out that an alternative is Silicone, and/or Sika polyurethane adhesive. While I need to research their 'yellowing' and Sun/UV resistance, is there any other ideas or glues people are using to cope with hot environments?
