I was in my local Lowes Home improvement store this past week and saw PVC boards. They are white, but can painted to any color. It may be a more permanent option for you. https://www.lowes.com/search?searchTerm=pvc+boards
Found replacement "vents" at a local boat place, so that`s done.
What I was looking for and found was this type of edging.
I tripped over a pair of Smart Tabs and added them on the weekend...LOL
I also stripped the "covering" off the dash and it`s down to the aluminium and looking for a material to cover it.
The deck is on hold....
Thx for the help!
