Filling engraved letters...Help needed

[soundguy.paul]

I have an aluminum plate that has engravings for an electrical switch (Up, Down and Logo). My question is how would you suggest I paint the plate White and fill the engraved letters and logo with a Blue color? The engraving is approximately 1mm deep and wide. I thought about filling the engraving with the Blue wait for this to dry, then apply wax (crayon or candle wax) then sand and clean the plate. then apply the white paint to the entire piece. if I heat the backside to melt the wax and clean off the wax and white paint from the engraving...

Has anyone tried this or have a better method?


Thanks
paul

I've been very happy scraping powder coat powder into the letters and baking. It's ok to bake multiple times. You could cover the letters you dont want filled with tape while you fill something. You could use the special high temp tape and leave it on, or just use the regular stuff and peel it. Just fill the grooves full; it settles a LOT.

I fill my engraving with black lacquer paint, allow it to dry but still soft then carefully wipe with a thinner moistened rag to remove the excess. Also crayons of engraving filler are available.

The old solution was 'lacquer stick'; the new variant is 'paint stick' and Zoro and other suppliers can get it in blue.
That's just to fill the gaps, you'd have to put a white base on, and rub the stick into the engraving after, wiping excess off
with a bit of elbow grease...

I used to paint hundreds of etched or engraved items for a local silversmith and sign maker. I would paint the infill, let dry to just past tacky as John suggested, but instead of a rag we would use a page from a telephone book wrapped tightly over a small rubber block. The telephone book pages were chosen because they’re lint free and would not scratch the polished surface. A small pad, kind of like a stamp pad actually, was used to moisten the paper just a wisp to avoid streaking. Change the slip of paper after every pass. A 1mm deep relief should be no problem, but I would make sure there are no rough burrs on the edges of the lettering though or the paint and your wiper will hang up there.

much easier to not do the white.
But your method seems almost feasible. The problem is heat on new paint ...

The way I did the lettering on my machine was using a paper towel rolled up tight and folded over.
I dabbed the raised letters.

So your engraved area is the low area, so dab the high area.

or if you can engrave after. Paint first let it cure it takes a while, or add hardener to your paint (oil based).
put a masking over the plate, then engrave, paint the engraving.. remove the mask...
that was too easy...

third method. Get a paint pen... if you have a good hand apply the raised or engraved using the paint pen...
