For starters, this question isn't necessarily for a specific car. Having said that, I have a 5th generation Subaru Legacy (2010-2014), as pictured here:
I have some rainguards to install which includes some clips and double-sided tape that is pressed against the chrome trim. However, since the rain guards are slightly transparent, I want to black out or delete all of the chrome trim first. I've been considering using plastidip or paint on the trim, or possibly having them wrapped with black vinyl prior to installing the rain guards. But, I'm concerned that I could possibly be compromising how secure the rainguards are attached to the vehicle.
Accounting for securely adhering the rainguards and ensuring a durable solution in general, what is the best way to black out or otherwise delete the chrome trim before I install the rainguards?
