I'm guessing you have a rubber roof on the Pace. If the existing patch job is sloppy, gently scrape/peal off the old caulk and re-apply an EPDM roof sealant (Dicor or Alpha brand) as neatly as you can. The holes should be small, some screw holes for the mounts and a larger one where the coax passed through. Alternatively, get some Eternabond tape and cut small pieces to cover the holes.
You can use a cloth dampened with mineral spirits to clean off the residue before applying new sealant or tape. Just dampen the cloth and rub - do not pour on. Too much solvent will loosen the adhesive that bonds the EPDM to the underlayment.
