DECALS!! For free! Using plain paper and krylon clear, I was able to make some cool decals for the yota. Took a few tries and a bit of experimentation.
1) size some JPG image files and print (in reverse) on inkjet printer in high res on plain paper
2) Trim to correct size
3) put a base coat on model. Clear is best, but I used dull-coat.
4) spray a light but covering coat of krylon clear on inked side of your image
5) lay image in correct location before the spray dries, tacky is best (really only get to do this once, can't move the image again). Krylon will dissolve inkjet ink so not too much spray...
6) the clear spray will dry as you gently but firmly press image down. Make sure it is all the way pressed down, corners and edges too. Use wax paper to keep fingers from sticking or leaving fingerprints (see my test image) Heat with hair dryer on low or medium, alternating between pressing down and heating until dry.
7) once dry and cool, soak with water for a few minutes , and then gently rub off dissolving paper.
Tips:
White background is best for images that also look good on white paper!
A clean smooth background makes for best image transfer, so a coat of krylon clear dried before applying decal would be best.
Don't rub too hard, you will remove parts of decal (although on my white test plastic piece, I rubbed really hard and it does not come off)
Since I was going for abused old look, I was happy with the sub-optimal ink transfer on the blue door...
