Resin 99.9 Fast Ver.

I have used this builder for a few times now and find it so easy to do overlays. It self levels beautifully (put a thin slip layer on first) and lasts for 3-4 weeks (on me at least). It also files and soaks off easily. In the image attached with this review, I used the Neo Base Gel (low) first, then this builder, then did mini designs using colours I-002 (red) and I-057 (green), finishing with the Resin Top Gel (low)

This was my first time trying gel overlay so I wanted something with a thick viscosity to have more time applying it. This one did not disappoint, very easy to work with even for beginners like me. It self levels with gravity and it gives a beautiful glossy finish.
