I have had 2 front maxton front lips break on me . One was due to a deep puddle of water, the other was my fault. I had to drill different holes to get the second lip on. I want to get another, but before I do I want to fill some of the holes. Will Bondo adhere to the plastic? I’ve used it before on a fender but never on a bumper. Or is there anything else you guys recommend?
