It hasn\u2019t let us down yet.</p><p class="MsoNormal"> </p><p class="MsoNormal">M1 is a available in several opaque colors and grey is the most common. Sometimes we want a good quality clear sealant to put around conduit fittings, where our conduit enters buildings, etc. We used Geocell 2300 in the past and I don\u2019t have anything bad to say to it but our current supplier doesn\u2019t carry Geocell products. More recently we\u2019ve tried Chemlink Clear sealant but I\u2019ve already seen signs that it doesn\u2019t hold up well in the elements \u2013 it seems to peel off the surface it was installed on and turn brown relatively fast.</p><p class="MsoNormal"> </p><p class="MsoNormal">Does anyone have a good multipurpose clear sealant that they like?</p><p class="MsoNormal"> </p><p class="MsoNormal">Best,</p><p class="MsoNormal"> </p><p class="MsoNormal">August</p><p class="MsoNormal"> </p><p class="MsoNormal"> </p></div></body></html>
