I'm a seasoned veteran of these roller jobs before using Tremclad and the technique just like he said. Always came out great!!! Especially when you live in an apt complex and can't make too much of a stink in the building. It do work good!

One note though where I have to disagree... I went to repaint one of my cars that were rollered in Tremclad, this was years ago too, and when I sanded the tremclad, it found it clogged the sandpaper up bad and found it very gummy...(rust paint never really hardens, and thats why it rolls out so smooth) maybe the paint has improved over the years but my experience is that if you ever decide to repaint it in a proper automotive paint then you'll have to strip the car down...

I have used the Duplicolor to spray too, that worked awesome as well...
