Need help!! May have trashed my boat gel coat :-/

Ok so I bought a 2000 Moomba Kamberra. The guy never washed or waxed the boat from what I can tell and it had a ton of hard water stains down the side at the water line. I used Meguiars #67 compound to remove the stains and it left the boat hazy in some areas, I went back with some Mothers Carbanua Wax and it left the boat a hazy white where I waxed it!! Is the gel coat trashed or did I do something wrong. I used a multiple speed orbital buffer to compound and just a towel to wax on and off. Any help would be great!!
