hey so i was at the local auto part store and came across "turtle wax ice shine like sealant" i have always used wax so i was looking into trying a sealant and this was one of the only ones i came across so i figured i would grab one. before using i decided to see what every one thinks about this. alot of what i was reading was people comparing to "meguiars paint protect" i didnt even realise that was a "sealer". so what the deal with these 2 products are they both true sealants ment to take the place of wax or i hear some put wax ontop of sealant anyway. any one use these how do they compare? i have always leaned towards meguiars with alot of things. but looking at price TW was about $20 for 4 fl.oz. MEG. paint protect is $10 for 16fl. oz. so if they same thing diff. companies why such a diff. in price. any info even if you got a product that better that both of these would be appreciated
