I used a roll of heavy duty black tape on my boats enclosure to repair/rebuild a badly damaged corner of the heavy canvas so when it came time to replace or repair the boats gunnel bolsters, I chose the many times cheaper option to use the heavy duty white tape in overlapping strips along the 4 foot length. While it may be a little short in aesthetics, the resulting job should last the rest of the boat's or my life and looks good enough to have garnered positive comments. Well worth the price.
