CEEDOG should be getting a sample of 1z vinyl rubber care very soon to do a review on.
Nice matte finish , possibly semi gloss, and absolutely water resistant. It will last through the rain and carwash's. and will absolutely not run onto the paint when it gets wet when used on trim. The only way to remove it is with APC.
This is the best product I have ever found, even though its a thin spray. I'll be honest and say that I prefer a gel or cream like opti-bond, but none of them live up to the water resistant durability of the 1z product.
The 1z has "advanced german polymers in it" that are patented and is also "streak free". (qoutes from back of bottle). Its also "water based".
I do plan to get my hands on some of the Ultima product in the near future. so i'm interested in a durability test between the two, which i believe CEE-DOG will enlighten us to. although i'm guessing Utlima might have the advantage as its labeled as a trim "sealant" and the 1z is a two step product that also cleans. but only a review will tell.
