X's 2 on the Top Gun fabric for a boat cover! I'm on my 3rd Top Gun boat cover on 3 different boats, 1750 Lund Tyee, 1850 Lund Tyee, and 1950 Lund Tyee Grand Sport. These covers are the BEST. I trailered many hundreds of miles with each of the covers and they held up perfectly.
On my current 1950 Tyee, the cover is now 2 years old. The shop that made if for me said that the latest version of Top Gun is called Top Notch. I forget all the reasons he liked it, but one of the reasons is that he could seam weld some of the seams. This latest cover ran me about $1100.00. Worth every penny. The shop used all existing snaps on the boat but added a few more on the bow.
