This morning I had time to install door sill guards. I have some free time while I’m at work. First thing you are supposed to wipe the surface with rubbing alcohol but I forgot it at home. So I used streak free glass & window cleaner made with vinegar. Cleaning the surface helps the guards stick. The guards have 3M tape that help them stick. Only thing I didn’t do is measure. But I think I did well. I could’ve had measuring tape to make sure everything is aligned and even on both sides. Hopefully they will stick on and last. I can always pull them off and replace the two sided tape. Both sides and front & back are competed.
