[R-390] Panel Engravings

[Bernice & Al]

All,

My couple of cents worth. (in Canadian funds) I done  an R-390  a few years 
ago and  had the same problem. What  I finally done, at the recommendation 
of a friend who said that,  "the main active ingredient in most paint 
strippers evaporates very fast and especially on a hot day". What to do. If 
possible, strip on a cool day outside. Put the panel in a plastic bag. Pour 
the stripper inside the bag and over the panel. Close the bag and press the 
bag against the panel and let out as much air as possible. Seal the bag and 
let soak like this for about twenty minutes  or more. Then use a brass brush 
and scrub vigorously. I Cut the bristles down to about 1/4 inch. This  gives 
a stiffer bristle and seems to be more effective. Inspect each letter for 
paint residue and use your favorite type of pick to remove any residue.

Done a Fair Radio R-390A Bluestriper about 4 years ago and did not have the 
same problem. The primer on the R-390A was, if I remember correctly, the 
conventional yellow color. On the R-390 it was a dark gray color. Don't know 
if this significant or not.

And that's my 2 cents worth.

Al
