If you do not like the white-ish surface appearance on your part, you can return it to all purple to make it aesthetically pleasing.
- Spray gun (http://store.preval.com/collections/preval-sprayer/products/preval-sprayer)
- 99%> Isopropyl Alcohol (IPA)
- Baby Oil
NOTE: Keep in mind that this oiling step is only for display parts. Oiled parts will not cast well.
Make a small mixture of IPA and Baby Oil in the bottom of the paint can. Mix by volume, 70% IPA, 30% baby oil. The two liquids have very different densities and will separate over time, make sure to mix it thoroughly before use.
Hold your part about 10 inches away from the spray nozzle and give it a few (3 or 4) light coatings of IPA/Baby Oil spray. You do not want to saturate the part. A light mist to make it a little wet.
Allow the part to dry and become all purple again.
If you think you need more purple, add another coating.
