Just another question...

i got myself a Subaru WRC Japan Rally version...together with the photoetche...this is my first time getting the photoetche..and i came across the instructions...for the stencil for radiator grille...it says...i should not use spray paint....i don't have a airbrush set...all i have is the tamiya spray cans....can't i use the spray cans?... :dunno:

Should work, why not... Just easier to control the "blast" with an a/b. Very small area to spray. Same with tyres - the paint should stick just as well, just mask very carefully.

I haven't tried it myself, though. But on the small chance that it does not work, you've not lost anything. If it works, look at what you've gained... ;)

For stencil work, spray cans are just too heavy.

The grille lettering on the Subaru is cherry red though, there isn't a spray can of that color.

If you are careful, you can take some spongy foam, like what is commonly used for packing material. (I keep the foam blocks from my Starter brand kits.)
Set up the mask as if you were spraying, but lightly blot the paint onto the screen with the foam. You want the paint on the foam almost the dryness of dry brushing, just a little wetter.
It will take a few applications to get the full vibrancy of the color.
Let the paint fully dry between coats and do not remove the stencil until you are done.
You may consider using white as a base for the first couple coats to brighten the red color if it is on a black screen...
If it doesn't work the first time, a soft toothbrush and some thinner will clean it up for another try, but they usually give you plenty of screen in the kit... - Mark
