I have a full bottle of PERL and only used once on plastic trim (with good results). I haven't tried it yet on tires. What kind of durability are you getting? Any white residue after a rain?
Durability is actually quite good in my opinion. last time I applied it was in January, and the tires have since been through a few snow storms and some rain. The shine lasted a little over a month and a half (like I had just applied PERL that same day). In march, the shine started to fade but the tires still looked and still had some sheen to them. They started gathering dirt etc and fading/turning brown towards the middle of April. I've been planning a detail for the past few weeks but the weather on the weekends has been pretty bad so haven't had a chance to clean up my vehicle. Planning on using PERL on the tires.
For comparison, I was using Meguiars Hot shine tire foam previously, and while that looked good initially, the shine would fade away in 1-2 weeks.
