Tub Surround Repair

Hello everyone, I am new to the list, but would appreciate any assistance you can give me. We have one out-of-state rental home. It is 9 hours away. Our tenants our moving out on Jan 31 and we have another tenant ready to sign the lease on 1 FEB. Our problem is that our outgoing tenant's just informed us via phone that they damaged the tub surround. The tenants had a lit candle sitting on the soap dish shelf of the plastic tub surround. The candle burned down to the soap dish shelf and melted a hole in the shelf about the size of a dime. I am only driving up in order to clear the outgoing tenants and sign the new lease with the new tenant. So, I will not have enough time to remove the old surround and install a new one. Does anyone know a method to repair this hole? The surround is one of those plastic four-peice types. I just installed it two years ago just prior to the current tenants moving in. It is not a fiberglass surround. I am thinking that there may be some sort of epoxy-type repair kit that I am unaware of. If someone can give me the brand name and which store to look at, I would be very appreciative. Thanks in advance, Tracy
