Zofchak..... this sanding pen. You use it on the little nicks and door dings even if you see no rust? Then seal with a primer? Or just get the body paint and touch it up. (if that is possible)<br>I have read this post over and over. I would like to get at the little dings and prevent some thing going to a worse scenario.<br>I do have some rust on the rack of my van. The wrong bolts were used in some of the connections and there is a bit of rust started there so I want to prevent some thing worse up there too.<br><br>Brass is better to sand with than the steel wool? and finger nail polish can seal good enough to prevent rust? <br><br>Thanks this is a good post.<br><br>
