HELP... What works to get yellow streaks off of Fiberglass

Hey all. I was all excited to get my newly painted aluminum back on my TC (renovation) It is all up, I stand back and think, all I have to do now is wash the fiberglass cabover and roof and the outside will be good as new. Great!

Well, not so fast, the yellow streaking will NOT budge. I bought and tried the fiberglass cleaner that the makers of "Dicor" sell. Didn't even lighten the yellowing. I know this thing is 40 years old, but it wasn't that yellow when I brought her home just less than 6 months ago.

I pray someone has a solution to this. I purposely painted the aluminum siding separate from the camper as I didn't want to paint the fiberglass as well. Of course painted it is an option, but the fiber glass was in really good shape (at least I thought)when I bought her. Any help would be appreciated.

Moved to Tech Issues forum from DIY.

    Goad you got it done! I was going to suggest Sof-Scrub With Bleach. Yes, a kitchen product but the fiberglass boat detailers seem to like it.
    Just found the FSR on Amazon at a very wide variety of prices.

    Toilet Bowl cleaner didn't work... clorox clean up is only good for mold and mildew... Dicor fiberglass cleaner made even more yellow streaks.

    My savior was a blue gel I bought called Davis FSR fiberglass stain cleaner. AMAZING is an understatement.

    I use toilet bowl cleaner on my fiberglass boats to get the ring around the water line off. Only been using it for 30 years but I'd try a small area first.

    L.A's Totally Awesome, from the $1 Store and sometimes WalMart may remove some of it. If you already tried the fiberglass cleaner it may be set too deep. Paint may be the answer.

    Rubbing compound with an orbital buffer may help. If that does not give you satisfaction you at least cleaned the surface for painting.
