Here at OBO we want you to get as much use as you possibly can from your kit. We often get asked whats the best glue to use on foam…we used to advise contact adhesive, but we have just discovered a great glue made by Loctite for “hard to bond materials”. Its called Loctite Plastic Bonder and bonds to OBO foam like a bad boy! The consmer pack contains an activator and glue and bonds to OBO foam superbly. You should be able to get this product from your local hardware store..here is a link to product on the Loctite website. If you cant find this the Loctite code is 770 primer and 406 glue.
