303 Speed Detailer, 16 oz | Cleans between washes while enhancing gloss and protecting exterior surfaces.

I tried the other "Graphine" based detailers from 303, but on my black C8 Corvette they always left streaks that were really difficult to wipe off. The Speed Detailer works much better. After I wash the car, I go over it with this detailer and it really shines. I have also used this detailer with the 303 clay mitt on my 911 and it worked great. I use the 303 car wash, tire dressing, wheel cleaner and aerospace protectant (instead of armor all); all in all 303 makes really good products. I have really only had sub-par results from the "graphine" line but I only tried it on a black car.

Hi tech car finish. Super easy to apply. Keeps my car looking new. Can do a small area or the whole car. Will remove light dust without washing. Leaves carcsurface feeling very smooth and shiny.

Great item

I tested it out. It seems really great. But when I received it, it was in a wrap plastic it was wet inside like it was leaking

I ran across this stuff after owning a ski/wakeboard boat for several years. I used various 303 products for the marine application for which it was originally made. I have been using the auto detail spray now for a good 3-5 years and would not consider anything else. It is extremely easy to apply (to a clean/washed car) and makes the surface very slippery like on of the best wax jobs you've ever seen. I've tried all the other off the shelf stuff, and some are similar, but inferior. I've even used the very expensive Zaino products and still prefer the 303 line of products superior. Never leaves streaks, does not take much at all and very easy to wipe off for an amazing shine and slipperiness. Even after using many coats of different waxes, apply this as a topcoat spray. The only moderately mild comment I'd make is after the car gets rained on, this stuff seems to come off easier than I though, but the underlying wax will still give a nice bead of rainwater and it just takes a few minutes with hardly any effort to do the car again with the detail spray -- If I'm in a real hurry, I'll just do the horizontal surfaces (hood, roof, trunk) and windows. Best stuff I've found yet for both the car and their marine line of stuff simply can't be beat. Bottles and packaging have changed a few time over the years, Just make sure it says "Automotive Detailer Spray"

Works well. Slick. Combine with their touch less sealant. I swear it helps the sealant out between washes. Noticeable in the rain as the water beads up and gets blown at speed.

Great speech detailer, nothing fancy except the shine it leaves. Water beads, easy maintenance between applications.

I applied this to my truck while in the garage and cool. Easy application. Went on and easy with no streaking. Used it on glass and all exterior parts. Worked well on all. I didn't use it on the interior because of the smell. Can't believe I'm the only one to notice this. If you like the smell of mosquito spray you're going to love this stuff. Come on 303, if your going to make a product for interior and exterior at least make it bearable to live with.

Bought it for the incredible protection. Much cheaper than ceramic yet provide almost same level of gloss and superior heat and UV protection.

Best stuff on the market for a quick Shine without scratching spray on wipe off no streaks

303 never disappoints and this product lives up to it absolutely 100%. I have never felt my car so slick. Only downside is that it wears off after a strong power wash but it's wonderful to apply on just after a wash!

Great level of gloss slickness once applied and buffed off

Outstanding product!
