Honestly they don't care how or even if you repair the vehicle read Nuke's post above, perfectly acceptable. If however you have a Lien holder they might want to know what you're doing since in reality they own the vehicle not you. As long as you don't try to claim the damage a second time (Insurance Fraud is a Felony) the insurance company really doesn't care what you do.
