ok...talk to me about sealant to wax. i've always used liquid wax....currently i have a half bottle of adams and i've been fine with that. i hand wax and do not own a buffer (mainly cuz they're costly).
Sealant v. Wax - the basics:
The simple part of it comes down to what they're made of. A traditional wax is going to be mostly carnauba and may have some bees wax or other natural waxes in it, mixed with oils, silicones, polymers, etc. Waxes can run such a wide variety of composition that its really hard to put a blanket statement to all of them. For the mostpart you'll get decent enhancement, some filling/masking, and moderate durability out of a wax. Where they start to fall short is in the longevity department especially in situations with high heat... even a really good wax is going to start to evaporate around 160* and they're typically not that detergent resistant either so its generally recommended that you use wax on garage kept vehicles or ones that don't see harsh weather.
Sealants on the other hand are man made. They can be made of a number of synthetic polymers and engineered to do any number of things. A sealant (on average) is going to provide much better resistance to the elements and longer lasting results due to the higher heat resistance and ability to stand up to detergents.
It used to be that you'd choose a sealant purely for protection and not see much enhancement in gloss/shine. The 'deep wet' look was more wax territory - but more and more the gap has been closed. We developed Acrylic-Shield (as an example) to not only be a super durable sealant, but also to provide gloss enhancement more generally seen with wax based products. Its a really nice balance of the two parts of the equation.
NOW - depending on how wild you wanna get theres also the option of layering waxes over sealants and whatnot - but thats a whole other discussion.
Also, be sure to recognize one simple fact - won't matter 2 squirts what you choose to use if you don't first properly decon and correct the paint - so clay (or clay media) and polish (with a machine you cheap bastard) are on the 'must' list. 99% of the shine and finished look is in the prep work - I don't care what wax or sealant you choose it can only work on enhancing whats there and if whats there is a swirly, dull mess you won't see much improvement.
