• Just lightly sand the underside of your fender to rough up the paint some and apply the aluminum strips (making sure you place some cardboard between the clamps and the finished side of your fender so you don't scratch your paint) about 1/2 inch from the edges of the fender right below the subframe toward the bottom of the fender with epoxy and let cure.
• Put some masking tape on the outside of your fender to keep from getting any bedliner material on the finished side and use some acetone to remove any unwanted bedliner material while it's still wet.
• Paint over the whole underside of the fender incasing the strips and the braces that are already there and make sure you fill the lip of the fender completely with the truck bedliner material.
• I made the thickness on the sides just thick enough to cover the strips encasing them and thinner on the top of the fender. I found it easier to lay the fender on it's side to paint the sides where your trying to get some thickness.
• I add about three coats on the sides on my fender You can add and remove the subframe while you work on it, so you can tell where to add more or less material. Then just remove it to paint. I painted the whole underside of the fender even under the subframe( there is plenty of room) just thinner under the subframe rails.
• When your done you will have created another inter fender bonded to your steel fender. Make sure you don't get any material on the bolt holes.
