    I had some serious scratches that my 2017 SX240 sustained when I was in Lake George, NY last week. The scratches were caused by a fender tired to a post that got blasted with sand in a storm.

    I got brave and wet sanded with 1500 and then followed up with 2000 grit paper. I don't see any more scratches. I then used 3M High Gloss Gel Coat compound on it. I brought back a shine but it is still a duller shine. I have 3M Finesse It which I put on by hand. Still the shine is not there. I did the compound with an electric buffer using a 100 percent wool pad.

    It has been damp and very humid here, could the weather be a factor. Any help is appreciated. Yes, I watched tons of videos on line but I can't get the results.

    Thanks

    Wool pads are fairly aggressive and are typically used with more aggressive compounds. I use my wool pad with Mcguires M105 Ultra Cut and then a foam finsihing pad with Mcguires M205 finishing polish to give it that showroom shine.

    Exactly ^^^^
    The 105 would really help in between sanding and buffing.

    Agreed, switch to a foam pad and an orbital or D/A (dual action) buffer if you were using a wool pad with a rotary buffer. Wool pad and rotary buffer very aggresive. Time to use a polishing compound as said above, and then wax.

    Thank you for all the help. I will get an orbital buffer today.

    I did 1000, then 2000, then 3m heavy compound and it came out like new. There were marks from the previous cf numbers.

    Here is a great link I found on a sailboat site some time back. It was written by a guy who details boats for a living. The article is soup-to-nuts on how to bring your boat back to showroom (or better) condition. It includes cleaning product suggestions, orbital polisher pads recommendations and how to use them, along with a step by step process with pictures. I have used it to bring back some fairly battered used boats to like-new condition. You even get advise on buying the right orbital polisher.

    Finally got her done. Sanded with 1500 and then 2000. Used the 3mHigh Gloss Gel Coat Compound to bring back some of the shine back. Then I used a Maguire's #4 cut cleaner and polish to get it better and then Maguire's Boat wax. It came out excellent. It was my first wet sand and it took a lot of time for me but I saved $300. A boat detailer wanted $500.
