Is there a guide and/or any tips etc for fitting a rear Zender style bumper valence to a standard bumper without the risk of damaging or scratching it & to ensure correct fitment?

Got some Tiger-seal if required

Thank in advance

It's pretty much straight on from what I remember.

Maybe some clamps would help too, but that may have been because my original bumper was damaged.

Otherwise, should be an easy job

you should be able to test fit it and it should hold onto the car without anything holding it on , usr some screws on the ends inside the wheel arch to hold it on to the bumper
