I'm thinking of installing a clear bra since I've been getting a lot of rock chips on the bumper. I noticed Lexus doesn't carry an OEM clear bra. Any suggestions for aftermarket ones?

For those of you that have it, how is the maintenance of it? Is it easy to clean? Any peeling or fading of the film?

 

I had a Ventureshield clear bra.
Ventureshield was recommended by my bodyshop buddy and other vehicle forums.Ventureshield is said to be better than 3M.

Great quality but like with all clear bras,the edges are a pain in the **** to keep clean.Especially on a white car of which I had the film on.I love white so I''ll pass on any clear bra installs.A clear bra will work much better with dark colors,IMO.
No other problems with the Ventureshield.Clear bras scratch pretty easy so care has to be taken when cleaning the unit.
