Squeeze the trigger and go. I laid down a 1⁄8-inch bead per the instructions. You might also want to wear gloves when working with this stuff. It won’t hurt you; it just doesn’t like to come off. Set the wheelwell in place and install the screws. I started at the top, and then I did the bottom ends and then the rest. I cleaned up the excess adhesive now while it was still pliable. The next stage is some bodywork and a coat of red paint. You can see just how neat these wheelwells are. They have a nice smooth flow to them and would look good in any bedside that needed them.
