When I first tried this, I bought both the trim conditioner and the tire gel. It took me 3 hours to do one coat of the cladding with the watery trim conditioner, and even that was after ripping the sponge off the bottle and using my own hand-sized applicator sponge. Plus the end result was realy, really streaky. When I used the tire-gel over it for a second coat, it took about 15-20 minutes to do the entire cladding and it was much more solid, still slightly streaky, but a second gel coat took care of 95% of that streakiness.

My recommendation is to use the trim stuff for actual trim and use the tire gel for the cladding - not only does it go on real fast, it also comes with a much nicer applicator sponge.

You will find that it is all or nothing, you can't do just one part of your cladding because it will end up significantly blacker than the untreated cladding. One bottle of tire gel is more than enough to do 3 coats of all the cladding.
