[R-390] Cleaning?

[Barry]

Collin,

What you describe might be either alodine coating or MFP (multi fungal
protection - or something like that).  The MFP coating is rather
thick-looking (kind of like varnish) and is rather shiny when cleaned.
Alodined surfaces stay rather dull

If it is alodine, you can have it recoated.  I had this done to a couple of
R390A chassis recently and they really look nice.  The downside is I
couldn't do the backs without losing the lettering so they don't look as
good as the rest of the chassis.

Good luck,

Barry - N4BUQ

> Hello,

on some of the transformer cans and other chassis areas going to come off
with polishing with never dull? Is this good? What is a good cleaning agent
for a dull looking insides. I have also found a trick some may know. Some of
the transformer cans were crushed down from to much fastener tightening. I
made a wooden die to fit inside the can and have formed it back to original
shape again. Some of the cans look as if they came with no hole for
adjustments. Some one either drilled a hole or enlarged the hole rather
crudely. I have cleaned these up a bit also. Any help on cleaning chassis?
