“S-100 Engine Brite”-same stuff I use on the black engine of the Harley-Davidson. I buy it at the Harley dealer. Made in Germany-you know the Germans make good stuff!
I just used meguiars ultimate compound, and rubbed it in as hard as fast as i could. it does restore it, fine and dandy. but ive yet to figure out a way, to keep it, from fading again
I've used 303 Aerospace Protectant on all of the plastic and rubber parts. Made for marine applications.
It beautifies intensely and preserves as powerfully. Keep your boat, watersport equipment and outdoor gear shiny season after season
100% free of grease-producing silicone oils and petroleum distillates. Its matte finish leaves no oily or greasy residue, and also repels dirt, dust, sand and saltwater.
303 is good indeed but it is water based and does not last as long for exterior. i use it for interior diluted 50/50 with water.. actually my first choice for interior plastics is Prima Nero... if u can still source it somewhere.
303 user and supporter here as well. Not fond of the smell, but it's a good protectant.
Does little for returning an already sun damaged item to new though. I also agree that it's pretty poor at adhering to exterior parts. One rain and it's washed off.
Yeah that's the problem with virtually all these black plastic/rubber restorers - the results wash away so easily. A lot of the products even state that you need to re-apply them every few weeks but really, who wants to spend their time doing that over and over and over all summer long .... Reading about the need to do that in the instructions is what stopped me from buying the expensive 303.
