I too have the pewter hull on a 420DA. I have seen lots of blue hulls on Sea Rays and they seem to hold up as well as other colors. In fact, even with quarterly waxing, the white gelcoat seems to discolor more than the pewter part of the hull. Interestingly I think Sea Ray has discontinued the pewter on the 44 (nee 420) and your choices are now black, blue or white. Other than the tires on my car, I don't own anything black--Ugly. In salt water I think white or pewter would work best.
