I bought a 2002 Rialta QD last week. It has not been used much lately, and it has streaks running down both sides of the fiberglass body. I washed it and have been trying to clean off the streaks using a car polish called Nu-finish. It is readily available at auto stores, Walmart, etc, and does a pretty good job. It does take a little rubbing. Do any of you have suggestions for this cleaning, polishing, waxing, etc. I do want to keep it looking good.
