Plastic mounting strips for under fuel tank???

[Tiny]

I was going to install the new tank like this http://www.yachtsurvey.com/fueltank.htm and wanted to know if anyone in the west palm area had a lead on some plastic strips, let me know.

I'm thinking I might just buy a piece of the recycled plastic decking material they sell at Lowes and rip it into 1/4 inch strips.

Any thoughts appreciated.
