In the horse trailer world, push-on edge guard makes an outstanding fender trim & is used to prevent injury to horses tied to to the side of the trailer.
And let's just say---we are frustrated with the glue-on edge-guard used for fender trim! Either the horses paw it off, or the glue fails & it starts hanging off the fenders, leaving an ugly residue. This type of edge guard used as fender trim, with small aluminum clips inside, is the way to go because it is easy to install with just a rubber mallet. You can pull off what is left of the glue-on product & install this right over it. Once on, this trim will conform perfectly to the shape of the fender, and stay there.
It can be easily fixed, with no tools involved. If a horse paws a portion of it off, just push it back on again with your bare hands.
Measure the fender edge from where it meets the trailer in the front to the same place in the rear. (You will need 8-12 feet for each side.) Fender trim is priced by the foot & comes in one continuous piece. Don't remove the old product until your order arrives. You may want to secure each end with a rivet or small screw. Both trims are very flexible, but they are easier to handle in warm weather.
This fender trim fits from 1/16" thick fenders to 1/8" thick fenders with a nice, tight fit. Applies easily with a rubber mallet, with clips facing the back of the fender. If desired, you can gently squeeze it with pliers here & there for a tighter fit, and it won't leave a noticeable mark.
