Floor crack repairs, anyone may have tried?

[Silvermax]

I have a number of small and one or two semi deep cracks in floor of 1976 V20. I got a price of $1,300 for the glass work, but I found this company who makes a vinyl marine type non skid material that can be glued down and would flex with the boat, and not re-crack like a paint job would. It is from a company called All Vinyl Fabrics 877-618-4695.

It seems like a good idea after they sent me a sample. Has anyone done this or something similar?

thanks.
