Is there a specific sticker material that I can infuse into a part. The sticker will be rather small and this is a cosmetic piece where if they wanted weight reduction they can just take it out.  Just looking for something that the resin will not eat away or distort. I will do some testing to make sure the part still fully infuses in that section.

Vinyl works fine. As long as there are no sections where the sticker is about 3" with no gaps to let the resin through then there's no problems.
