The only issue with wax or sealants on fresh paint is the outgassing. You can get hazy clear coat is you seal in solvents that are trying to outgas through the paint. If you want to cut and buff the clear, this is a bodyshop technique, they've already done it, it won't hurt anything, as long as you use products for fresh paint that don't have sealants in them. Compound wouldn't, it's for cutting only, but as others have said if it has issues from the original cut and buff that the bodyshop did, why even think about working on it when you already paid them thousands to make it perfect. Just take it back.
