Using these mudflaps is simple. First, find the pre - drilled holes on your PDW Full Metal or Poncho fenders. Then, use the provided stainless - steel mounting hardware to attach the mudflaps. Make sure they're securely fastened. When you're riding on wet roads, the mudflaps will do their job of protecting you from splashes. As for maintenance, keep the leather clean by wiping it gently with a damp cloth. Avoid exposing the mudflaps to extreme heat or cold for long periods. If you have any issues, remember they come with a lifetime warranty, so you can reach out for support.
