RE: First Monokoting Experience: How bad is bad?
I agree with the Ultracote suggestion. I grew up with Monokote but the modern stuff is hard to use. Its not as forgiving as Ultracote, since it doesn't shrink as much, releases gases when heated so sheeting and two tone jobs develop a lot of air pockets, and thicker so slightly heavier, and you really have to work it around compound curves. I love its glossy finish, and it does seem to be slighty more puncture resistant. Wrinkles are hard to get out also.
Ultracote is not as glossy, shrinks at a lower temperature, and seems to shrink more, so it is easy to get out wrinkles. Additionally, if you go for multi tone "paint" jobs, it is much easier to avoid air bubbles over the first color. The only thing I have against Ultracote is that it can shrink and wrinkle under the sun
Good luck!
BTW you might keep the scraps of covering, comes in handy when patching holes
