For those that encountered 'streaky' results with 303 Aerospace Protectant: did you give the surfaces a thorough wetting before removal?
The instructions specify: "Spray on, wetting the surface with 303. Wipe COMPLETELY dry. Turn cloth over to a dry area (or use a second clean, dry, absorbent cloth) and polish to remove any and all excess. Following these simple instructions.getting the surface wet (not just damp) with 303, then wiping COMPLETELY dry.will give you a beautiful, like-new finish that repels soiling and stains and LASTS LONGER."
Seems as though a really complete wet-down followed by a very thorough dry-off might be key to attaining the optimal final result.
Don't get me wrong: I'm not calling anyone out as a 'not-so-thorough instructions follower'. I've never used this product but have a full bottle that I intend to apply for the first time to my new car's dash and interior plastics, so this is of particular interest to me.
I wanna give my car's dash the best available protection from the sun's assault and from the reading I've done on most detailing forums, most detailers seem to feel pretty strongly about 303's product lineup (which is why I bought several of their products). A new car's dash is only a virgin once: I wanna give it the best starting-out protection available.
