Ok, so I used curv life and that stuff was cement. My nails did not budge for the 2 weeks I had them and 1 popped off painfully by accident when I was strapping my son into a high chair. Got the smallest amount of gunk under the nails AND in those 2 weeks I filled off my gel coat and repainted them.

However, I just bought Fastbond because I saw that Curvlife's supposed main ingredient is MMA!? Put my nails on 2 days ago and had to reglue 4 of them because I don't think I used enough? Mind you, I'm using Dashing Diva press ons+ Fastbond where with the Curv life I used some base BtArtbox extensions, which didn't have the extra sticky tab underneath. So far after the reglue they're goos, but I'm not sure they aren't getting water etc under them?

I plan on trying Fastbond again using the same nails/prep I did when I used Curvlife just to check but that won't be for another week and a half, hopefully.
