Beer and paper...that's funny! That's Bobp!
If they haven't been used much or installed only a couple of times they haven't had a chance to relax a little and can be fairly difficult. And yes, heat makes them a lot more pliable. Practice also helps. I've installed side panels in a 30 knot breeze and 4' seas to keep the spray out. We were already soaked!
A couple of things that will help though...
1. Make sure the top of the bimini is centered on the arch tubes. It will tend to work its way over one side or the other. You may find one panel goes right on and then you can't get the other side on. You can even mark the tubes with a sharpie for future reference.
2. Once you get all your panels on , adjust front and rear straps so they are perfect for next time.
3. yes, zippers first, then snaps, then velcro. Front, sides, back.
4. The side curtains seem to be the toughest, and sometimes easier from the outside. Pull down with one hand and snap with the other. Work from windshield back.
5. Best snap lube, easy to use: lip balm. Sunscreen optional. :wink:
6. Install everything and leave it up for a time. Especially if you get some warm sun. Will relax the clear plastic and make next install easier.
7. Roll panels, don't fold. Very important, otherwise you'll get permanent creases. Some even roll old bath towels in between the panels to protect from scratching. I dunno, mine are 4years old this year and still look like brand new.
8. If you still have the plastic adjust buckles for the front straps, consider replacing them with stainless - they will break.
Stainless top hardware, buckles, snaps, toggles, velcro, etc. :
www.sailrite.com. Don't buy the cheap nickel plated brass parts they have at West Marine = junk. Have at least a few replacement snaps on hand - it's not unusuall to get a couple that pull apart.
If you use your top a lot, plan to remove it once a year, clean it with 303 fabric cleaner and a soft brush. Treat with their fabric protectant. It's what Sunbrella recommends for their fabric. Will restore water repellency and prevent sun damage, rot, and mildew.
