I've used it for about a year now on the bumpers and trim. I like it. I haven't noticed any streaking either. I clean the trim monthly then apply the 303 with a pad and wipe off.

303 is good but I only use it to dress my engine after an engine wash. I use Opti-Bond by Optimum Polymer Technologies on black trim and tires. Great product! If you want a more durable solution try CQuartz Dlux. It's a coating that lasts up to 1 year.

I recently started using on the engine bay of my 4.8i
Sprayed on all plastic covers and rubber hose, it doesn't leave greasy residues like other stuff. Seem to dry and stay clean.
Then I went real mental after realising how good it was and started applying all over including cv boots, suspension plastic parts, etc.
