My 303 aerospace observations:
It's almost odorless. That quality alone makes me want to use it. GRADE: A

It's pretty hard to apply without getting streaks. The instructions on the bottle say to spray it directly and wipe off. hmmm, the nozzle on the spray bottle is a jet. That would be messy to say the least. My technique was to get a towel damp with the stuff and wipe it on. Anyone else's recommendations? Maybe a rag with a large knap? The door texture is the *****. GRADE: C

It's a little more shiny than I was expecting. Not super glossy but obviously not transparent. It did gloss up the flat textures, bummer. GRADE: B-

It's slick, just like all the others. I should have not applied it to the steering wheel and shifter. I suppose it will wear off over time. GRADE: C

Protection? hmmm... get back to me in a couple years. GRADE: N/A

Is this stuff considered the best?

anyway,
I also used the 303 cleaner. It took the blue jean stain off the seat. It was raining when I picked up the car so I guess it transferred some of the dye from my jeans to the seat. It worked rather well. Most anything probably would have cleaned it. It has a mild odor, a bit funky, but certainly no fruit, pine or chemical smell. 303 claims that it leaves no residue. GRADE: B+

Someone on the board mentioned using a brush to apply the 303 to the door panels. I plan to try using a sponge soaked with it next time I apply it.

 

 

Use a coton terry towel to apply it, Helps with the streaks, and make sure you let it sit on the surface for at least 5 min. Buff with a dry terry towel.

To shiney for you? Just add 2-3 oz of pure water. Still to shiny, add 4oz.

 

I was hoping that by using the 303 and avoiding the armour all, I could avoid or at least lessen that damned hazing you get on the inside of your windows. I had none whatsoever but I applied some of the 303 to the dash this past weekend and sure enough...HAZE! I guess the only way is to just not use anything.

 

Water!!! Nice tip! Thanks Brad4rdHay. I'll try it tomorrow.

Haze from heat, sun or out-gassing? Can't be worse than the grease stripe on the side windows! <jus joking>

I'm just going to use a damp cloth to wipe everything down. I've done that on my other cars and its not the best, but it stops the window haze. God, I hate that haze...

 

We don't get haze from armor all or 303. Dunno what you guys are experiencing.

 

When I lived in Utah, I used to get haze from armor all all the time. I moved to Washington about 3 years ago, and haven't seen it since. Maybe the hazing is related to the climate in some way.

Anyone else seen something like that before?

 

I got window haze before using the 303, no change since then. I'm a week into the use of 303, and I agree, it's a bit shiny, especially on the seats, and streaky.

What I love about it is what it does to the tires. It's a week after the wash, 2 days of rain, parked outside every day, and the tires still look great - like satin.

I used the 303 for my CS touring interior and like it very much. According to the instructions (somewhere), I applied it to all plastic, rubber, leather surfaces. Which means lots of surfaces. The one place I did not apply the 303 is the material above our head (I do not know what it's called). By touch, the material seems like either plastic or cloth.
Should I apply the 303 to that material?

 

I probably won't apply it to the headliner material.

My question: did this stuff make the leather seats slippery? I don't want to be sliding around while i'm driving agressively.

 

I tried it on the leather and didn't like it so I cleaned them off and used Lexol. IMO much better.

I don't intend on putting anything on the headliner.

 

I got the 303 fabric guard and applied that to all the cloth, and carpeting. Brad4rdHay recommended it over something like Scotch Guard for protecting those surfaces.
