PS did test car waxes and none were to impressive especially on gloss ratings. 3M Ultra Paste and Collinite Fleet Paste #885 stlil came out on top for gloss.
Unfortunately PS does not really understand waxes and advised the use of a machine for application and removal of Collinite.
Please DO NOT use a machine to apply or remove carnuba wax or you will defeat the entire purpose and protection of the wax. Collinite goes on and off very easily if you know what you are doing PS does not unfortunately as many don't..
A little misting bottle of water, a foam applicator done by hand and microfiber rags for removal are all that is needed. DO NOT let a carnuba dry totally before wiping off and do not apply in the sun. Properly applied and properly removed Collinite is very easy the problem is most don't apply or remove correctly.
I have tried tons of car wax's and none has stood up as well as Collinite paste wax. I've even tried some of the very expensive carnuba's like P21s, Pinnacle Souveran and many others.
I would love to find a product that out lasts and out shines Collinite on fiberglass but as of yet have not found it...
