Re: is it possible?
Rustoleum will work just fine, if the boat is prepped and the primer and paint are applied well.
I haven't waded in on too many "smallboatlover threads" because, frankly, they wear me out.
I think that the guys here are tired of your lack of progress in the general "listening and growing up" part of life.
Look, all of us were young guys once, believe it or not, who did generally dumb stuff over and over again. Most of us got over it by listening and sometimes believing in what other people told us. On this forum, there is about 20 centuries worth of boaters' accumulated knowledge and experience. If you can digest and listen to what they say, you may progress and the guys will cut you some slack. Otherwise they will keep treating you like a red-headed step-child.
We have one poster, coolguy, who started posting when he was 13. He initially had some of the same issues with general English grammar and the inability to use the shift key, but he rapidly started to get with it and write in complete sentences and use punctuation. He also learned, by listening and asking well-thought out questions, to completely rebuild outboards and boats on his own. He progressed, and still is progressing, and will probably be nobody's burden as he grows up.
Hopefully you will also progress as he did.
