Now I understand the hype of 303 Protectant

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.

 

What other products have to use as an underhood dressing/protectant?

 

303 Protectant looks great but its durability is poopy.

 

Meguiars Hyper Dressing at 4:1 also does a great job

 

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.....

 

Emile, Megs hyper dressing is better for you? in durability?

 

303 is great, trim, rubber.

303 and ONR are my favorite two products!

 

FK 108 for me!

 

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

 

I use Meguiar's All Season Dressing. holds up pretty well for me.

 

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 am also a fan of the 303 aerospace.

 

Been wanting to try Megs Hyper as the price is great!

 

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.

PERL works well for me too.
