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.

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

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?

Getting back to "what is hard wax?" M&H tells me it is also known as Jeweler's rouge, a stick of a very hard wax that contains a very fine abrasive such as iron oxide (reddish brown) and is used with a cloth wheel to polish metals (or gelcoat).
It is totally different from softer, protective waxes such as paste wax, Carnuba, etc. and is used as a polishing agent, not for protection.

What is recommended for polyurethane finishes?

Non silicone containing good quality (preferably UV filtering) car hand application polish is ideal for PU.

The rouge provides polishing action and the wax carrier is deposited on, and worked into the surface by the resulting heat of polishing. This seals the gelcoat.
After completing, I usually go over with Scotchgard Marine Liquid wax to do final clean up and provide added protection. I think M&H does the same thing.

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.
