I may be new in covering, but, I have tried almost every type and any ideas that have been told to me and by far the best seems to be heat and good covering to start with. Any ARF you buy needs to be completly gone over with a good sealing iron on high or close to high. Someone befor said to almost melt your edges together. Thats the only way I know to keep them there. Lapping the leading edge will of course keep the wind from dragging the covering off. Trial and error has shown me the best way is the old way.
