Re: [DML] Sandblasting DeLorean frame - advice needed.

[Ralf Philipp <enteklemmer@xxxxxx>]

Hi John!

My frame was stripped by this method (thermal paint removal). IMO this 
is the best method for our frames. Most of the coating will be converted 
to ashes with this treatment. In some places, there will remain some 
kind of black slag, so the frame needs to be sandblasted after the oven 
treatment, anyway. But this is much less labor than sandblasting a frame 
with intact epoxy.

After that, the best you can do is dip galvanizing the frame. I did it 
myself. Don't forget to drill holes in the hollow sections, so the zinc 
can flow in and out again. (I would drill these holes before the thermal 
paint removal, so the result of the thermal treatment will be better in 
the hollow sections). Drill diameter at least 10mm. Two holes per hollow 
section: One hole at the lowest point, one hole at the highest point of 
the hollow section. Where exactly is the lowest and highest point? This 
depends how the frame will be dipped into the zinc, later. So you must 
decide this, and assure that the people at the galvanizing facility 
follow your instructions.

I recommend dipping the frame in its normal position, but "nose low" (as 
if you car would be standing downhill on a very steep hill). In no case 
should it be dipped in horizontal position (like it would stand on a 
flat surface). This could lead to a warped frame! Be sure that the back 
of the frame is at least 1m higher than the front while dipping. The 
higher, the better.

I was very satisfied with the end result :-)

hope that helps,

Ralf.
