Adheasive difficult to install

3 pcs of new adhesive in the kit. The small pc for the bottom was easy to install as described. The 2 for the sides were horrible. it was NOT possible to remove the “bottom” plastic keeping the top on to help install. There was no “colored” plastic on these parts except a small tab at the ends. It took me as long to install the adhesive as the whole rest of the project took.
