Re: [DMCForum] sand blasting vs bead blasting



Jan & Greg,

My flaps were never painted.  Instead they appear to have a very light
plating (zinc or cadmium?) that has rusted through in places.  I asked Al,
the owner of Classic Auto Air Manufacturing, if he could re-plate them.
He
didn't like this idea as he explained that it is a sacrificial layer that
would eventually wear off again.  He normally bead blasts them and gives
them a clear coat.  Since I was just looking at his plating tank, I
thought
he would be anxious to use it.  This guy is very straight forward &
honest.

The flapper doors are made of sheet metal and the hinges are very simple.
They just roll the edge of the metal over a steel rod.  I might replace
with
a brass rod.  Now that I've thought about it, I know this local fabricator
who might be able to make new flappers out of SS.  Now that is being anal!
:-)

Classic Auto Air is in the process of making reproduction evaporators for
our D's.  The last I heard is that he was waiting on a shipment of
pre-bent
tubes.  I don't like the PJ Grady replacement I got because it has copper
tubes with aluminum fins.  Al said that I should expect an efficiency loss
of 6 to 8 degrees F if I used it.  And if I used R-134a, the combined loss
would be even worse.  The one advantage to using copper is that it lasts a
lot longer than aluminum.  I think the trick is to install a screen in the
cowl inlet to keep leaves out & don't park under trees.
