POR 15 is the absolute best for rust control. It actually likes tight rust. With a garden sprayer you can reach spaces not accessible to spray gun. I also drill holes in end of rockers to reach from both sides. Not cheap at $150 for a 4 quart pack. Depending on what you plan to coat may only need 1 or 2 qts. Goggle POR 15 to find sources all over the US. Any restoration shop worth it's salt uses POR15.

There are many access holes for air blowing and high-pressure water cleaning so I think they can be cleaned pretty well but they probably would still have surface rust. Without having an option to dip the frame area in paint would spray painting through the access holes be adequate? Does anyone have other suggestions that would result in decent protection to the interior surfaces? Thanks, Carlton Schroeder Eagle River, WI (2" snow yesterday and temps about 15 - 20 F below normal) [Non-text portions of this message have been removed] [Non-text portions of this message have been removed] ------------------------------------ To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/Yahoo!
