Im very happy with my perl. My first and only trim product so far though. Made my almost new interior look better than new. Haha. Plus, i think i bought the liter bottle, maybe? Thats gonna be enough to last me a long, long time.
Mostly I use ultima and Wolfgang , very similar to me . solution finish if need to bring back something faded then upkeep with ultima . I recently used c4 and it was awesome but I f'd it up , would like to try it again but it's pricey . dlux is next on my list to try .
I've been very pleased with the ease of use and longevity after applying CarPro DLUX to all my exterior trim months ago. This stuff really lasts...great product.
