Tire gel on ABS plastic tim pieces and Tonneau covers

[danEz_yoda]

I'm using the black magic Titamium tire gel from Autozone and while it takes some work to get in a bone dry tire, it does last about a month. I'm wondering if anyone has used it on ABS plastic pieces (mudflaps, bumper plastic, plastic tonneau covers, etc).



Any problems doint this?



If so what is a good long lasting product that will do the same thing?
