Scott Thanks for your insight into my wing skins, But you may have missed the small part that said I replaced my spars. YEP, SORRY I MISSED THAT, BUT THAT IS A GOOD THING ACTUALLY THAT YOU REPLACED THE SPARS. I find it difficult to see the difference in getting a bond with the spar, if you cut the skin , then sand off the skin and flox, Vinyl Ester resin bonds better to its self than to wood, BY PARTIALLY SANDING THE WING SKIN RESIDUE FROM THE SPARS, YOU ARE ACTUALLY NOT DISTURBING THE PREVIOUSLY ESTABLISHED BOND. YOUR IN A SENSE, ADDING PLYS TO THE OLD SKIN. Also by sanding off the flox and cleaning up the spars, wouldn't you remove those Micro cracks? HOW FAR OR DEEP IS THE MICRO CRACKING? HOW DEEP DO YOU GO WITH THE SANDING???? In the case of Micro Cracks, how do we then, tell if the spar material we buy in the first place to build our spars ,do not already have Micro Cracks?? BUY MATERIALS FROM A QUALIFIED SOURCE. TREAT YOUR BUILD MATERIALS WITH DUE CARE. I will discuss your comments with a aircraft structural eng. THAT'S AN EXCELLENT IDEA. MAKE SURE THAT WHEN YOU SPEAK WITH ONE, MAKE SURE THE ENGINEER HAS SOME FORM OF COMPOSITE EXPERIENCE, AND DON'T "SUGAR-COAT" OR MINIMIZE WHAT HAS OCCURED. BEST OF LUCK TO YOU.
