I have used Zymol in the past and have always been a fan. I used their cheaper line of waxes though, never their higher end. I just purchased swisswax from swissvax.us and the stuff is amazing. It goes on SO easy and just buffs to a shine. I know swissvax makes a wax specifically for white cars, but I just bought their basic wax (onyx I think is what it is). I would recommend the swisswax to anyone. They have a good line of products. I use their leather cleaning kit and it works really good too.
If you are looking for a good wax that is super easy to apply I definately think you should give swissvax a try. I would get it off amazon though...same distributor, but free shipping.
