I am using por 15 silver. Spraying it on.
I have degreased it (marine clean), and etched it (metal ready)
and have applied 2 coats on some areas of the floorboards.
got to get more paint tomorrow to finish. the por 15 should
seal the floorboards until next summer when I will do a light sand
and prime and paint. It will be cool weather soon and I will be heading to the florida keys for the winter. so "Boxer" will be waiting for me when I return in the spring.
