really depends on what rustoleum you actually used. to be honest though duplicolor, rustoleum, zinsser and a few other name brands are all made by sherwin williams and not very good. but some food for thought i have had better luck with opaques of rustoleum, and duplicolor than clears but even then i have ran into bad batches of said opaques ( colors in case you dont know). now in regards to clears, it is best to stay away from EVERYTHING sherwin williams makes, i have had several projects require stripping because after 30, 60, and 90 days respectfully i could still strach the clear topcoat and grab enough of that little scratch to literally completely peel the clear off of the project ( in fact i have a few flakes from one of the projects i peeled the clear off of 90 days ago and they are still soft and it is now going on 115 days).
