Ill start this with Im from Texas and dont know about rust.....it scares me. Ok, thats done. I now live in Colorado and its something I will have to deal with. Bought a 89 K5 and the driver side kick panel, inner rocker and in front of rear tires is rusty. Same on passenger side but not near as bad. The drivers side is ate through in a couple places (finger size holes up to a baseball size hole in front of driver rear tire) and the passenger side is just pretty severe surface rust. There is no carpet in this thing, Im not trying to restore it just dont like rust. What are my options here? Id like to at bare minimum stop it. Ive read that the rust converters (whatever they do) arent what they used to be. My plan was to spray/roll/whatever bed liner in the floors and then put some heavy universal truck bed mats down to quiten the interior from road noise some. No plans for carpet as we will be leaving the top off of it during most of the summer and we get frequent 30 minute rain showers up here. I appreciate the help!
