Best of asking the bodyshop.
Polishing is fine though whatever - it is waxing and sealants that are the problem and big no no. Selaing the paint prevents it curing. If however it has been baked properly it may on the other hand be fine to do it now. If not 30 -90 days without sealant/wax.
If this is the case dont use SRP as it it maybe a mild polish but it contains the sealants too. Chances are the parts will have been flatted and polished already but using bodyshop sealant free polishes. Most of the Meguiars pro line polishes are designed to be used on fresh paint.
