Wax...
My 2 cents....
Stay away from anything that has Petroleum Distillates in it. It will look nice, but down the road it gets absorbed and will turn your gel coat yellow. If you are a non-believer check out some boats at your Marina and you will see the ones that have used Petroleum base waxes. It happened to my parents boat. Doesn't show up immediatley, but years later after using it every couple weeks, BAM, yellow tinted gel coat. Not what the Docotr ordered!:hat:
