Get Rustoleum Peel Coat. Stay away from Plastidip. You can spray it on like paint, and peel it off if you change your mind.
A 3rd friend's Silverado's front bowtie was broken, so I got a cheap one on eBay and painted it with Plastidip for his Christmas present. Didn't turn out too good. Ended up peeling it off twice before it was an acceptable finish.
They've all held up great! Started this back in the fall and have had many car washes and they look good as the day I did it. And if you ever change your mind, it just peels off pretty cleanly.
That sucks you had a bad experience with PlastDip, but based on my personal experience, I'd lean toward if before using the Rustoleum, simply due to the amount of time and $$ Performix has into the product line. It is virtually their entire business at this point where the Rustoleum is just a tiny percentage of their profit. My fear would be that it might be inferior to the PlastiDip although I personally don't have any experience with it. I am probably the most experience member here with PDS though, having sprayed dozens of parts on numerous vehicles including spraying my entire Av twice and 3 other vehicles in their entirety, the first time I sprayed my Av was in 2014 (the product has come a long way since then too) and it was still in great condition when I peeled it last fall (dozens of members here have seen it and can attest to it's longevity if applied correctly.) I only peeled and re-sprayed it to change colors and spray it again. I believe the Rustoleum is only available in select colors, in your case it wouldn't matter as I assume you are going to use black, but PDS is available in dozens of colors, with different additives and different sheens/glosses.
Do be weary though if you use one brands base coat (color) do not use another brands top coat/glossifier as many have learned the hard way that the chemical makeup of the different manufacturers products are not compatible with each other .Whichever you might choose, (PlastiDip, Autodip, Rustoleum, Spectra, Duplicolor)stick exclusively to one product line.
The relatively low cost and ease of application and removal make all of these viable options for experiment.
On another note. I'm not completely sure, but are the side moldings on the LTZ not 2 pieces? Can just the chrome portion be removed? Both of my Avs are LTs so I've never looked at the LTZ trim in detail, but it appears that the chrome strip is an "add-on" to the LS and LT trim.
