If it is just a scratch in the clear coat it can be touched up/filled with clear nail polish to reduce the appearance. It is through to the actual flake and color its pretty tough to repair other than professionally. Chalk it up to being USED and not paraded around on a trailer!
If the scratches aren’t to deep you can sand and buff them out. I use 600, 1500 wet sand then 3m finishing compound on a wool buffer. I just did my whole boat, it looks awsome. Any deep scratches will have to be fixed in a shop.
