Ranked #3 in Best Car Wax

Chemical Guys Butter Wet Wax

4.4

$19.97as of Jun 7

Chemical Guys Butter Wet Wax is the value carnauba in this group: it melts onto paint, wipes off in minutes, and leaves a warm, wet glow that rivals waxes costing far more. Durability is its weak point, so treat it as a fast, affordable maintenance wax rather than a season-long coat.

Strengths

— Natural carnauba delivers a warm, deep, wet-looking shine
— Smooth liquid creme spreads and wipes off fast, even for beginners
— Lightly cleanses light scuffs, tar, and overspray as it applies

Watch-outs

— Carnauba durability is shorter than synthetic or ceramic options
— Best as a maintenance or topper wax, not a long-haul coat
— Shine is gorgeous but does not bead as aggressively as a ceramic

Higher ratedRanked #2 in Best Car Wax

Collinite 845 Insulator Wax

4.6

$21.95as of Jun 7

Collinite 845 is the durability king of this group, a 1936-vintage carnauba-polymer wax that detailing forums trust for four-plus months of protection through salt and sun. Applied thin, it is easy to use and machine-friendly; it trades a little show-car warmth for protection nothing else here matches.

Strengths

— Exceptional durability, commonly reported at four to seven months of protection
— Carnauba-polymer blend holds up through winter road salt and summer heat
— Liquid formula is easy to wipe on and off, and is machine-friendly

Watch-outs

— Must be applied extremely thin or it becomes hard to buff off
— Shine is durable and reflective but less wet looking than a show carnauba
— Old-school formula benefits from a fully decontaminated surface first

How they stack up

Chemical Guys Butter Wet Wax

The warmest, most show-car shine in this lineup and the best value, but it gives up real durability to the Collinite 845 Insulator Wax and the synthetic Meguiar's Ultimate Liquid Wax. It is also less hydrophobic than the spray ceramics, the Meguiar's Hybrid Ceramic Wax and Turtle Wax Hybrid Solutions Ceramic Spray Coating.

Collinite 845 Insulator Wax

Out-lasts every other wax here, including the Meguiar's Ultimate Liquid Wax and the spray-on Meguiar's Hybrid Ceramic Wax. It gives up some of the easy spray convenience of the Turtle Wax Hybrid Solutions Ceramic Spray Coating and a little of the warm gloss of the Chemical Guys Butter Wet Wax, but nothing in this group protects longer.
