I’m doing plywood (1/16 birch) leading edges on the Center section and will be doing on both lower wings also. (Hope to not have to uncover the uppers right now so they won’t get plywood leading edges now) I have the 1/16 plywood cut to size for the center section. (Figured I’d try small first!). My questions are 1) I’ll use T-88. What thickener is preferred to add to it on the ribs? 2) how long do i soak the plywood before I form to Center section? (In just warm water? Nothing added to water?) I’ll be doing this in a heated building. I think I have the rest figured out but was curious on a thickener to help keep the T-88 on the ribs as it’s pretty runny. I’ll squeegee T-88 on the inside of the plywood. Use straps and 1x2s to keep the plywood in shape while it dries.
