Author: Bill Stevens (Stevens AeroModel) I hate to sound like I'm selling snake oil here but this glue deserves your attention! Not quite thin and certainly not as thick as medium CA glues. This product will penetrate tight joints while still filling any gaps that may exist in the structure. I've found the 100XF to perform better than any other CA glue I've tried (and I've tried them all) when bonding carbon fiber to balsa or carbon fiber to carbon fiber. For building our models I suggest using the NHP Flash thin CA glues for initial parts tack prior to covering apply the 100XF to all critical joints for a bond that simply cannot be matched. Please use a CA glue tip for more precise application of this product.
