I decided to run an updated comparison test to my original test (link to full write-up) since I may not have allowed for enough cure time before buffing the products in question.
As before, the interior section was cleaned with Detailer's Pro Series Total Interior Cleaner (link to DP TIC review). I then taped out 2 columns and made a 3 row grid in order to test the difference in cure times/buffing @ 5, 10, and 15 minutes post application.
First up, 303 in wipe form:
Next up, Detailer’s Pro Series Interior Surface Protectant:
DP ISP was given a quick shake before use, and 1 shot was sprayed onto a clean foam applicator pad.:
Starting from the top, I buffed the first row after 5 minutes, second row after 10 minutes and the 3rd row after 15 minutes cure time and then removed the tape:
With flash:
This time around, the results are much closer and far less dramatic then my first comparison. Waiting 5, 10, and 15 minutes didn’t yield any variations. This is a good thing since you wouldn’t want different shades of product appearing after buffing.
There is however, still a difference:
From certain angles, 303 produced a darker finish then DP ISP.
For me the biggest take away is the need to wait at least 5minutes before buffing either excellent product. Since this was the interior of my wife’s car I decided to remove the test area completely and use DP ISP throughout as part of a long term test.
