How to Repair Scuffed Gel-coat?

Wife saw some brown dots on the side of the motorhome that were tough to remove, so she used a green scrugie (I know,a big no no!) to remove them. Now I have several scuffed up spots on the exterior gelcoat and on some graphics. Is there anything I can do to get that high gloss shine back on those spots, I know I won't be able to repair the scuff marks on the graphic's.

Thanks for any tips!

  • Thanks B.O.Plenty, they are small spots so I will try it by hand first then give it a waxing and hopefully get the shine back.
  • Polishing compound will work just fine by hand. If you have a larger area a buffer will speed things up a bit. Be careful not to rub too hard on decals as it will take the printed colors off.

  • Also Bar Keepers Friend: comes in a can similar to Comet. Less abrasive than most polishing compounds. Usually powder form, but I've also found it in liquid form. It's the preparation product of choice for the "Red Max Pro" users. Have to wash/rinse it thoroughly to insure the wax goes evenly.

    Red Max Pro, now replaced by ZEP, is a floor polish found in Lowes or HD. Puts a wonderful finish that lasts for at least a year, much longer if not subject to the hot Florida sun. No UV protection. I eventually had to strip it off my Class A. I don't use it any more, but it has a large fan base of dedicated users in the RV community.
  • I will try the polishing compound, can I apply it by hand or does it need to be applied with a buffer?

    Thanks!

  • There are lots of better choices than toothpaste or tooth powder. You don't see any body shops using that. Get a good automotive polishing compound, the white Dupont stuff in the small round can works good. It's available almost anywhere they sell car wax.

    Believe it or not Toothpaste works! Preferrably non gel type.


    If you can find it...tooth POWDER works lots better

    If they are too deep for that, try rubbing compound, then polishing compound.
    You'll still need to wax it when done, because these just took off any protection your gelcoat had.
    I totally agree!

    Walmart sells polish. They used to sell Scratchout, now a Turtle wax product in a green squeeze tube....maybe it's a plastic bottle.
