I'm attempting to do a 2004 Donzi Daytona reupholster and I'm having a challenge with the curved gunwhale (side wall) pads at the front of the boat wrinkling too much. They're built at about a 75 degree angle, with 3 seperate foam pads running the length of the pad. Is there a trick that anyone could share to make sure that these curves tighten up? As you can see, it's only the lower two layers of white that are puckering.

Hard to tell without seeing it close up, but it looks like the padding under the white is a little weak from age. Adding even a little extra padding, like as little as 1/4" can really help. Another thing that can help is not putting the vinyl directly over foam. Foam can grab the backing of the vinyl and not let it slip into position. There's two ways to handle that, one is to glue on a thin layer of dacron, and the other is to use plastic over the foam. I don't like to use plastic because it traps moisture, but sometimes you have no choice.
