3M Finesse applied with a Milwaukee right angel polishing motor will absolutely cut thru flat sun-faded gel coat and get it back to a gloss with color. Don't overdo it as there is a limit to how much gel coat you can remove.
PB Buster or Kroil are two of the best penetrants made for your worst fastener that's stuck. WD40 is on every shelf so you'll have to look at NAPA or some high end stores to find them.
