Without pics it's impossible to make recommendations that are not guesses...but assuming you have swirl marks and minor scratches in the clear coat only, so far only the suggestion by @bigtwin is on the right track (other than contact KEF). Waxes and polishes wont help, even though products like Zymol genuine carnuba waxes are very good at protecting surfaces once corrected.
Menzerna also makes very good paint correction / polishing products.
But true paint correction cannot be done by hand. You need a professional grade machine, not a cheap rotary polisher you might find at Walmart.
A proper auto detailer might be a cheaper alternative to buying the materials and gear, and acquiring the skills to do this, unless you already have them.
