My tip would be fix the rust, and paint the areas only (even if you roller the areas........) if you plan on eventually having good paint on the car, then you're just making it far worse by putting that stuff on. It will just be more labour when it comes time to do it right. That will get you by for the time being without having a bunch of dings and rust anyways...

For the amount of work it takes to make it look good, you may as well spend money on proper material and have a good job IMHO. Doing it this way involves ALL the prep, and time of a normal paint job (plus more time if you're actually going to buff it. A paint job will never be as rough as a roller job - so wet sanding that down will easily take 2 to 3x longer then necessary) so if you're going to all the work of doing it, it seems rather pointless to me to use a matieral that will not last.



Can it work? Sure it can....just won't work for very long.
