[R-390] My last major hurdle in restoration Paint and Engraving

[Tisha Hayes]

What I did was after priming the front panel is to fill in all of the
engraving with plaster of Paris. Gently wipe that down until the plaster
residue around the engravings is clean and the plaster is hard, then paint
the panel.

After the paint dries I used a dental pick to pluck out the plaster. It left
behind very deep engraving (with only primer inside) so I could letter the
panel. If you did it right you need some sort of guide to figure out where
the engravings are as it may be impossible to see after painting.

Usually a few pokes with a sharp dental probe and the plaster cracks and is
easily removed from the engraving.

I use Tempo Aviation Aircraft Enamel, A-1105 Medium Gray (spray cans) as my
paint. After 3-4 coats, oven baking and a few days curing it looks
spectacular.
