Hard wax v/s liquid wax

Hi,
Can hard wax be replaced by liquid wax application? Of course silicon free, as well as other harmfull adds.
Although i've seen guys maintaining their gliders purely on applying liquid wax regularly, i guess it wont seal & protect the gelcoat as well as a good anual hard wax buffing.
¿Any advice?
Thanks

Liquid wax is good for maintaining but is not a substitute for the sealing properties of hard wax on polyester finishes.
Hard wax buff, then maintain with liquid wax.
UH

Please name a few brands and types of typical "hard wax" for use on gelcoat.
Thanks.

Menzerna seems to be the pick of the bunch here in Europe
G18 first and something like M5 or P175 to give it a glossy finish

I have had good results recently with Big White Hi-Temp Paste Wax. Put in on thin by hand or smooth pad at low rpm with a random orbit machine. Let dry to a haze, hand wipe off with a clean cloth. Buff with a finishing pad at higher rpm.

As with painting, surface prep before waxing is critical for best results. Remove hard water stains (ehite viniger usually works), polish with an ultrafine compound like 3m Finesse-it II (white color). Be careful of the new 3M ultrafine compound for cars that is blue in color, it can stain white gel coat if left on the surface more than a few seconds.

According to my research, pure brazilian "Carnauba" seems to be good for the job.

Generally, we believe that the smoother and more glossy the surface, the better. Is it actually supported by a scientific research? How about the 'stickiness' of certain substances with regards to the airflow, e.g. caused by electrostatic charge? Any thoughts?

A golf ball has many small dimples over its surface, to make it more "slippery". So how would this principle apply to a glider?

Read up on turbulators. They're not needed on modern airfoils, but were
useful for preventing flow separations on older wing sections (Wortmann)
and at the hinges of control surfaces:

- I've seen turbulators immediately ahead of the aileron hinges on
Discus 1s

- fitting them ahead of the rudder hinge on a Grob G.103 is said to
improve rudder response

- my Std Libelle has full span turbulators under the wing, just in front
of the undercambered part of the lower surface.
Streifneder sells them.

... and of course they work really well to improve airflow at low Reynolds
numbers (40,000 - 100,000).

Just ask any serious free flight model flyer. The first F1A I built with
a D-box wing structure flew like a dog until I fitted thread turbulators
where the rear of the leading edge and the front of the main spar were on
my previous successful open-structure models with entirely tissue covered
wings.

Except that ALL modern airfoils use turbulators.
