Custom Toyota TRD-like "Pro" emblem
Sorry there is no 2-sided adhesive included to keep cost to a minimum, they are shipped directly from Shapeways.
I recommend that you primer the model first with a few light coats of automotive primer, lightly sand smooth to remove any primer imperfections, then either plasti-dip or paint.
You can get high quality 3m automotive VHB acrylic #4926 from Amazon, this is the best cost to product ratio (roughly $20 for 5 yd.), you will need a small piece to cover the legs of the R:
You can also buy 3M two-sided tape, I cannot vouch for the quality, at any automotive store, wallmart. or home improvement store for about $5 a roll.
NOTE: It seems some of the colored versions are not UV stable (at least the green isn't) If you do not intend to paint them it has been recommend to at least coat them with a quality rattle can clear coat such as Krylon UV-Resistant Clear Coat
