I want to cut the back bench seat to make it like a split rear seat boat. My thought is that by leaving the center seat it would still keep the strength , and by having the sides of the back seat still there like corner braces would help too. Anybody have opinions on this? Also does marine text stick to aluminium good? I've used on fiberglass but not aluminium. I'm new to the site looks very informative thanks for any info in advance.
