i was wondering if the mar-hyde one step i belive it is called is any good at preventing rust it make's it into the black selant and i wanted to know if that would be a good choice for surface rust if i'm just gonna paint over it let me know about that and how it holds up or if i should stay far away from it thanks.

i used Metal Prep 79 and it worked great. 6 years and no rust yet. I used the one step last night actually, painting my buddy's trailer. We'll see how that turns out. I the one step then grinded, ,used more then grinded some more. Finally used it and sprayed over it.

POR15 doesn't *need* to be coated if exposed to sunlight. It doesn't do anything to the effectiveness of the product itself, rather it makes the gloss disappear and the finish just becomes matt.

Sure, you can paint more or the POR15 over it, just like normal paint. If its cured like that, it'll need a clean and to be keyed (rubbed back with fine paper) to give the next coats something to adhere to. POR15 is particularily fussy about this.
