[FWDLK] Spray-On Bedliner miracles / fuel tank senders

[Dave Stragand <Dave.Stragand@xxxxxxxxxxx>]

Hi All,
 
Is anyone out there familiar with the spray-on truck bed liners that
come in spray cans?  I've fallen in love with the stuff as a replacement
for undercoating.
 
First off, it looks just like undercoating.  That's great, especially
when trying to achieve the correct "look".  You can also use it for a
real undercoating base, and apply real undercoating on top of it for
increased protection.
 
Next, the stuff is impervious to just about everything I've thrown at
it.  On my test piece of steel, it's now survived a day in battery acid,
a day in carb dip, and a day in gas/carb cleaner.  It's based on Crazy
Glue, if I understand it correctly.  The labeling states that once
cured, it can only be removed by sandblasting, grinding, or intense
burning heat.  Now that's my kind of coating!  Plus, it stays reasonably
flexible to boot.
 
The reason I brought it up, is I just painted the DeSoto fuel tank with
it tonight, and I'm betting the stuff would be wonderful in sealing
small seeping leaks. (On the outside, not the inside.  I don't trust it
that much yet.)
 
While I was at it, I took apart my fuel tank sender.  There's not a
whole lot to it.  Basically, there is a wound cone of wire and a brass
slider.  In electronics terms, it's a simple variable resistor.
Cleaning up the slider and the cone made a non-functional sender into a
functional one in only about 10 minutes.  For those of you desparately
hunting a new sender, try cleaning up the old one first -- it might just
fix it.
