Ok, this sounded a little odd to me but im gonna ask anyways. I just purchased a PT 170 TX and the trailer is painted black so know its not galvanized. This Easter weekend i was at my uncles house and my cousin asked me if the trailer was galvanized. I said no its painted steel. He told me to make a habit of washing off the trailer everytime i pulled it out of the water and brought it home. I know this is normal for saltwater but im 5 hours away from the coast so i know he was talking about the lake. Is this true or is he a dumb a%$?
