Glitter Gal 3D Silver holo is very sheer. This was 2-coats with no top coat. It could have used three but I wanted to save on polish. To save on polish, I'd advise layering it over a silver chrome or white. I had no issues with application or dry time with this polish. My only peeve with this polish is its size. The bottle is very small, the size of a mini.
Here's how it compares to China Glaze's OMG.
Index & Middle: Glitter Gal 3D Silver Holo. Ring & Pinkie: China Glaze OMG.
Both have the linear holo effect. OMG has more of a silver pigment in it. Glitter Gal has a more pronounced holo effect.
Here's OMG by itself:
Don't ask where I bought it and how much I paid for it. I'm not saying!
Here's some other more widely available silver holographics in my collection:
From left to right: Glitter Gal 3D silver holo, ChG OMG, OPI DS Coronation, Milani 3D Holographic HD, Color Club Worth the Risque.
Index: 3-Coats of OPI DS Coronation, Middle: 3-Coats of Milani HD, 3-Coats of Color Club Worth the Risque, and Pinkie random holo glitter polish.
OPI and Milani are nearly identical. They have a scattered holo effect. They shine more in sunlight obviously. HD shines a little bit more predominantly than Coronation. Worth the Risque was a dud. I think there's different versions of this and I got the less holo version.
Glitter Gal 3D Silver Holo - can be purchased for Llarowe or from their Australian site, http://www.glittergal.com.au/
OPI DS Coronation - I purchased this when I was on vacation overseas. It can be found on eBay for reasonable prices.
Milani 3D Holographic HD - can be found in the Milani display at CVS or Milani.com. These are $6.
Color Club Worth the Risque - can still be found through most etailers or eBay. The holo effect is barely visible. I would not recommend.
China Glaze OMG - the OMG collection has been discontinued for 3 or 4 years now. These can found on eBay for outrageous prices. If you really need a silver holo, buy the Glitter Gal one and layer it over a silver chrome or the Milani version.
How do you feel about holographic polishes? Do you have any in your collection?
