Spray cans! <G> I've done many a guitar, speaker enclosure, or other
smaller item with spray bombs. Lot's of nice colors, and clear coats
for top coating at any decent auto parts store.
Actually it is, but you'll sand and rub a lot more. You also might need
to wait longer before rubbing. The flip side is that you'll have a
thicker layer to rub, before you accidentally rub through. For flat
surfaces, use a cork or wood sanding block. For the edges and gentle
curves, a felt block is good. Edges can be done with "tadpole" sanders
or foam (pink or blue insulation) blocks.
A neat trick on edges is to rout them, apply a thin coat of filler or
heavy coat of seal coat, then do another pass with the router.
The priming of the overall piece and filling of the edges follow the
same theory. You'll apply the product and sand most of it off,
repeating until you have a glass-smooth surface.
It fills the MDF. Other suggestions for sandable fillers that work
well for me include drywall spackle, modeller's "spot putty", or many
coats of shellac. Glue will fill, but it's difficult to sand.
Keep in mind during early experiments that an off-white, silver, or
machine gray will be a bit more forgiving with the final finish. Black
isn't the best choice on your first panel.
Once you're rubbing out color and clear coats, for a super gloss, you
can go up into the 1000-2000 grit sandpaper range, and finish with
automotive rubbing compounds.
The fun part of this is the lack of a downside. If you accidentally rub
through a paint coat, spray another on and continue! The raw material
is literally throw-away, it's not like you're ruining a rare exotic wood
if you screw up.
Have a good time!
I been wanting to try some of these type finishes but never
got a good reason...
Have you ever done any of this type ?
