No problem.
This is basically what I was talking about
:
You can find this stuff for sale everywhere. Auto parts stores, big box (WalMart and Target) stores, discount stores, even grocery stores in the soap and cleaners isle. The brand really isn't important.
Buy a bottle for only models and it will last you long enough to will half of it to your grandchildren.
For die cast model cars- Very handy because it is a weak form of silicon wax. Instead of spraying it on and letting it dry, wipe off and buff immediately after you apply it. I use a Q Tip (cotton bud) to apply it and wipe/buff it with either some old cotton from a tee shirt or a paper tissue (kleenex). Same process for clear plastic, just test first on a part you won't notice if you're also dealing with paint or decals. SHOULD NOT BE USED ON MATTE OR FLAT PAINTS, you'll never get the shine off of those parts. The wax should hold up for several years, as long as you don't display your die casts outdoors.
For clear parts in general- Should only be applied after the part is painted and glued in place. Provides a very shiny finish and also a minimal "hard shell" layer to protect the plastic from stuff like finger prints and dust. On small parts, use the cotton bud/Q Tip to apply and also to wipe off and buff. DO NOT use if you "dip" your clear parts in floor wax.
For plastic model cars- MAKE SURE the paint is fully cured and polished prior to use. Multi level paint work can take time to fully cure. Always test on a hidden part of the paint prior to use. Very handy if you're getting kits ready for a show/exhibition.
Gives gloss paints a "showroom shine" so probably not a good idea for most dioramas or Rat Rods.
