i am doing a car this weekend and i dont have time to order a polish. i was going to get Mother's Polish, but then i saw the bottle of Meg's #7 and i bought that. i am now reading on here that meg's 7 isnt really a polish and shouldnt be applied with a PC. should i get the Mother's Polish instead? i can also get a 3M glaze or step #2 of the 3 step Meg's stuff. edit: forgot to mention that i already have a bottle of #9 2.0, could i use that?
mothers polish:
megs deep crystal
megs #7
3m stuff:
what will be the best for me to use with my PC before applying a coat of NXT?
