It will have no effect, talking of a period of 5 years. The reason i used aluminium and vener, plus MDF boards is exactly that. Massive wood dont like changes in temperature. The method i use with contact glue and vener doesnt care. Its a rarely used combination, but if any big company is watching this thread, its gonna be copied for sure. I can only say what i said before . This method rocks ! Still, they nered to figure out the thinner \ glue respactables. LOVE It !!
