Finally got back to the boat today. So I read the instructions, brought my windex, acetone, and a small vacuum to make the surfaces really clean, and got to it.
The results that you can get on your own, taking your time, working with a partner on the template process, is pretty cool. There are one or two spots where I can see that distortion, either caused by deflection of the mylar, or my poor artistic skills, keeps me from hitting all the lines just perfectly . . . but I'll never tell!
Overall an excellent process working with SeaDek, as long as you're not in a rush. If anyone with a 282 Sailfish, probably 2001-2005 at least, wants to leverage this template and layout, PM me for the individual part numbers that were labeled on each piece, as well as the contact at SeaDek who worked with my process.
Will probably post back to this thread at end of season with feedback from use, cleaning, durability, and what the wife thinks!s
