Touring cars do take some hammer (depending on the driver
) but it tends to be in different place, the area above the wheel arch is prone to rubbing especially if running a soft setup and the front of the car takes the most damage from the bumper. but like Ian says this isnt the same as protecting the paint with laquer/ nitro block etc.

for added protection from damage I personally would recommend fender mender/ shoo goo as it leave a rubbery texture that offers really good protection from rubbing etc.
