This is professional auto glass glue, it is high viscosity ( thick ) , so a caulking gun will be required to apply the glue. If you using a regular ( not a professional ) caulking gun to apply the glue, please make sure to warm the glue up by using the hair dryer for 15 mins . Please do not stock it in cold place so the glue will freeze and very hard to apply.
