How do you paint transparent objects?

Recommended Posts

Hi Everyone,

 

I'm wondering how I should paint the following piece(s), it's the cockpit window for a Spitfire.

How do people generally tackle this?

I cheat these days, A set of canopy masks from Eduard or Montex or similar is usually available. Failing that, make your own with Tamiya tape and a sharp knife.

Thanks for that, I suppose tamiya tape is better than my cheap diy store tape for cutting out complex masks? I'll order some online.

Yes, it is. It's very flexible, so you can rub it down right into the angle between frame and window with a cocktail stick. You'll then find that as you angle the piece in the light that you can see really well where the cut line needs to be along the edge of the frame, because the tape is translucent. Use a very sharp, ideally new, pointed (#11) blade, and don't press too hard... you don't want to score the plastic if you can avoid it, just slice through the paper layer. Angle the tip of the blade into the V where the frame and window meet: if you try to use the frame as a "ruler" to cut along, it's too easy to drift and start carving the edge of the frame instead of cutting the tape. And if your Spitfire kit has some spare alternative windscreens for other versions that you're not going to use, practice on one of them first!

 

All the best,

Matt

Perfect! Thanks for the advice

I just place Tamiya tape onto the area to be masked and press it down with a wooden cocktail stick into all the corners. Then with a sharp pencil I mark the frame area, then remove the piece of tape and cut the "mask" with sharp decal scissors. Next I re-apply the mask I've cut back onto the canopy...

Remove the transparency from the sprue, clean it up and dip it in Klear

and leave to dry.

Put Tamiya masking tape on the surface to be painted/sprayed

Burnish it down

a cocktail stick is useful for this, but any blunt instrument will do

Take a sharp scalpel (you may get away with a knife) and cut up to the edge of the canopy frame

Remove the excess tape

and its ready for paint

This method works just the same on more complex canopies

Just apply the paint

Leave to dry thoroughly before removing the tape

When dry, remove the masking tape

I use a scalpel to lift a corner
then peel back

After the canopy is masked, first spray the frames with the interior color. Allow to dry, then spray the exterior color.

following that nice photo tutorial, if you're using acrylic paint, if any paint got under the masks you can usually lightly scrape away the errant pick with a wooden toothpick. The toothpick is soft enough to not scratch the clear plastic.

hi all .

             I bought a roll of 15 mm wide White Maskin' tape made by MT (Japan ) in Manchester's BIG Craft Store  this May

 

               This Tape sticks !..... is thinner than Tamiya and can be marked with a Pencil/Biro and easier to cut to shape.

                  ......... even use the stuff on my  CANNON Printer Cartridge after a refill .

 

                                                                           cheery "modellin'" mumbas !
