Actually years ago when I had my glitter rockets I was fanatical about wiping them down as soon as I pulled them out of the water. After having a spinal fusion last year I cant barely get into let alone out of the drivers seat of a bass boat so I switched to a bay boat, best move ever. Down side is its got acres of gelcoat. Now I just pressure wash it after every couple of trips and sometimes even use a scrub brush with a long handle and some Armor All Wash-n-Wax.
One reason I have always wanted a white boat. When my raspberry and sliver Ranger was new I did the wipe down routine. I just used a towel and sometimes Pledge. Pledge will make the clearcoat slick. Maybe that is what I need to do to keep the rats out of the boat.
