For this comparison test I'm going to use Detailer's Pro Series Interior Surface Protectant vs. 303 Aerospace Protectant on my 2009 BMW 335i convertible.
Prior to applying these two products, I cleaned the entire interior with Detailer's Pro Series Total Interior Cleaner:
(Click here for my comparison review of DP TIC).
Detailer’s Pro Series Interior Surface Protectant:
For applying DP ISP I sprayed 2 shots on a foam applicator pad. DP ISP was given a quick shake before use:


Note: I tried taking a photo of ISP on the applicator pad but had difficulties capturing a good shot. It has a slight gel consistency that is quickly absorbed into by the foam pad.
From DP ISP product page on AG:
303 Aerospace Protectant:
For 303 I’m using the wipe version. No shaking required!


From 303’s product page on AG:
Side by side results: After applying both products to the driver’s side door trim I waited a moment before giving them a quick buff to knock down any high spots and removed the blue tape to expose my clean control surface:
W/ iPhone flash on:
As you can clearly tell, on both the textured vinyl and smooth plastic trim surfaces 303 left the finish MUCH darker then ISP. I couldn’t believe it when I removed the tape. I figured it would be close, but not this dramatic.
Smell: Both 303 and ISP have a fairly neutral smell. ISP may have a very slight hint of banana but I couldn’t tell for sure.
Cost: Since I used 303 wipes, I’m going to base my cost break down based on the 32 oz size of 303 available on AG so the price is more closely comparable:
Conclusion: This is a tough one. Both products are competitively priced, don’t have offensive odors, can be used on all types of interior and exterior surfaces,and have UV protection from the damaging effects of the sun. Since both my wife and I have cars with dark color interior surfaces, I have to give 303 the advantage since it clearly makes black darker.
I decided to remove ISP from the driver side door and apply 303 to the whole surface as well as the dashboard and passenger side door. But used ISP on the rear deck and also in the rear passenger’s compartment. I’ll be sure to update this tread with any observations I have over the coming weeks.
A special thanks to the folks at AG for sending me a Detailer's Total Interior Combo kit as a surprise gift for coming in 3rd place in the “Post a Selfie” Facebook contest. I truly appreciated it. :dblthumb2:
Hope this review was helpful!

From 303’s product page on AG:
“Of all the products offered at the Autogeek, this one has to be the most versatile. Vinyl convertible tops, boat enclosures, tonneau covers, car bras, vinyl RV awnings, headlights, spa covers…these are just a few of the places that benefit from this protectant that contains an SPF 40 sunscreen.”
