21 </b>The lexan pieces have a protective covering that needs to be removed before assembly. When the laser cuts, the covering melts into the cut
22 edge which can make removal difficult. If you gently scrape the cut edge with a flat blade screwdriver, the covering can easily be lifted and
23 peeled off.</font>
24 <p><font face="Verdana" size="2">On smaller pieces the coverings can be more difficult to remove. If you have trouble you can gently scrape the
25 cut edge, then use duct tape to lift the covering off.</font></p>
26 <p><font face="Verdana" size="2">For further information on lexan, see <a href="https://wiki.lynxmotion.com/info/wiki/lynxmotion/view/support/polycarbonate-info-page/" target="_blank">this page</a>.</font></p></td>

262 outdoor terrain (sharp rocks, etc.) you might want to protect the bumpers from scratches. You can spray paint these parts with several thin
263 coats of flat black acrylic to add some scratch protection. You can also place a piece of black electrical tape along the bottom and first
