This stuff is killer. Cleaned up the engine bay of my mom's 2001 E46 with 1Z Blitz APC and protected the plastics with 303:
Good stuff I use it on engine bays, tires, vinyl, plastics, and leather sometimes works great and leaves a low gloss matte look.
I love Hyper Dressing, works on tires, interior, exterior plastics, under the hood etc..........you can get similar results and for a fraction of the cost, also the Megs instant detailer works too, also has Anti UV properties.....
I couldn't say, I have never tried Hyper Dressing my friend. Look into Vinylex, it is quite expensive but it has a similar look to 303, offers excellent durability, and it cleans and protects the surface in one step.
Ive gotten 3 weeks on a set of 33" mud tires with megs Hyper dressing, and that is washed twice..... its pretty good actually
Definitely worth getting 303 spray. I use it for my engine as well, not so much for the interior as I thing 1z cockpit premium provides a better matte look. But, 303 is awesome for engine dressing.
I go between Meguiars Hyper-Dressing and Chemical Guys Back to Black (spray can). Nothing can beat the awesome smell of Meguiars Hyper-Dressing, and nothing turns everything plastic as black as Chemical Guys Back to Black does, in my experience. Have yet to try 303 Aerospace on engines and compartments yet. Dan F
