I am alwats leary of putting on undetcoating as it can get pinholes cracks etc and trap moisture.  I have always used a number of different products dependimg on the location basically oil and wax based products .   For interior panels where i really want to penetrate cracks etc. I use Fluid Film.  For locations where i want something that dries a little harder such as in the beams on the underside of the van i use Transstar 4423.  For the exposed areas on the underside i use Waxoyl.  All of this stuff can be purchased in spray cans or bulk although Waxoyl needs a special kind of sprayer if bought in bulk.  I touch up once a year.

Subject: suggestions for truck bed or other product to refresh undercoating

Hi list,

        What modern products would folks recommend I use to refresh the undercoating on my Vanagon?  It was undercoated originally and in most places has held up. Still there are some places where I can feel it is thin.

I suspect there are both spray and paintable options.  I also expect some products last and others don�t.

Can folks send me product recommendations and application tips.

In most cases I�ll probably use some sighted help but I�ll need to do the prep and in out of sight areas I may paint some on myself.  All spraying is left to sighted helpers.

Tips appreciated.
