Durability & Protection

(Back to top)

Since this product is synthetic, it will last a bit longer than carnauba waxes but don’t expect months of protection though. According to reviews, durability will last as little as a week of protection to as long as a month. And also because of it’s synthetic composition, it offers a layer of protection against UV rays.

Ease of Application

(Back to top)

The Synwax can be applied by hand or through an orbital buffer, pour in a small amount (preferably a dime sized) on an applicator and work on a two to three square foot area. If you are using a towel as an applicator, turn frequently when it is soiled. Using a machine, set it at low speed then work the product in until it breaks down.

Ease of Removal

(Back to top)

Wait for the wax to haze before you start buffing it off, preferably using a microfiber towel. Though it won’t leave any powdery residue, it may leave some streaking which is more noticeable on darker vehicles. If it does streak, wipe off using a damp microfiber, or spritz the area with a quick detailer then wipe off.

Mothers describes it as a “crisp, sharp and glossy shine” as opposed to a warm gloss that carnauba waxes are known for. You might be asking ,what the heck is the difference? To put it simply, synthetic waxes offers a flat yet, mirror-like shine and a carnauba waxes give more depth, adds more warmth and gives more of a “wet look” to the paint. So often, professional detailers like to combine synthetic and carnauba waxes in car shows to get the best of both worlds.

Take note that this also contains light polishes that can remove light blemishes and oxidation, to remove moderate to severe oxidation and paint defects please use a polish.

Pro & Cons

(Back to top)


It does not have a ton of reviews online, but a majority rated it highly. Consumers like how easily it goes on and comes off, as one reviewer mentioned it cut his waxing time in half. It gives a great mirror like shine that is most noticeable on black cars.

Essentially, the formula of the Mothers 20016 FX is designed to improve the texture of the paint. A closer look at the composition reveals a few fundamental ingredients responsible for eliminating surface flaws and adding a layer of protection from the road and natural elements.


One of the negative comments regarding Mothers SynWax actually indicated that the customers did not follow the instructions. For instance, one customer complained that the black plastic parts (on which he mistakenly applied liquid wax) of his car became grey after leaving his car outside in heavy rain immediately after polishing. As the label clearly states that the product should be applied only on the paint coat of the vehicle, this incident is clearly not related to the efficiency of the Mothers liquid wax.

Be careful also that you don’t get this product in creases and crevices of your car, as it can leave a white residue that can be an eye sore.

The Mothers FX Synwax did not disappoint in terms of shine, ease of application and removal, being made from synthetic polymers it is should last longer than carnauba waxes but this wasn’t clearly stated in the reviews. Regardless, an affordable and good performing wax – just be careful not to get it on rubber or plastic surfaces. If you have own a black or a darker colored car you may want to consider this wax.
