I started out covering my plans with wax paper and had the same problems. I've switched to using 6 ml polyethylene sheeting. CA and other glues won't stick to it. Also, the thicker 6 ml sheeting seals well around the building pins and prevents even thin CA from getting through to your plans. I've built my last 3 planes using polyethylene to cover my plans. This stuff is readily available at Lowe's or Home Depot and one roll is enough to build a fleet of planes. Try it. You'll like it.
