| Problem of dealing with this kind of tail light parts is that it is almost impossible to duplicate the turning lights (if orange) and back-up lights. The only solution that I can think of, with my current skill, is to use a resin casting technique and duplicate the parts in clear resin so that I can paint the parts. In this page, I'll explain how to make a two-piece mold. | |
|
First, make a fence by using the Lego blocks and fill the bottom half with clay. Press down the parts so that there's no gap between the parts and the clay. |
|
I use Shinetsu KE-17. I've been using it for 15 years and I'm very
familiar with it. Conventional RTV silicone rubber should do the same job. The blue bottle is the catalyst. |
|
Pour the silicone and wait until it hardens. KE-17 usually takes 6-8 hours. |
|
Once silicon is hardened, dissemble the block and remove the clay thoroughly. |
 |
Flip the mold over and surround it with the blocks, then apply mold release wax so that one side of the mold doesn't stick to the other. |
 |
Mix silicone and catalyst, pour it in, and wait until it hardens. Once the mold is made, use a knife and engrave the grooves so that it won't trap any air bubbles. |
