Went through (3) 50# bags of fine/extra fine black diamond "blasting abrasive." The bags didn't say what the abrasive was made of.<br></p><p style="font-size:12pt;font-family:helvetica,arial,sans-serif;color:#333333;" class="default-style"><br></p><p style="font-size:12pt;font-family:helvetica,arial,sans-serif;color:#333333;" class="default-style">To get the finish as nice as possible, I need to do more finishing tomorrow. Went to The Tractor Store, picked up three bags of fine abrasive. This time, the Black Diamond bags say "coal slag," then goes on to warn never to use silica based (such as sand) because of the possibility of silica in the lungs. Looks the same as my first unlabled batch, though.<br></p><p style="font-size:12pt;font-family:helvetica,arial,sans-serif;color:#333333;" class="default-style"><br></p><p style="font-size:12pt;font-family:helvetica,arial,sans-serif;color:#333333;" class="default-style">Tell me, though, isn't there such a thing as "black lung disease" from coal????? So you get that instead of silica?<br></p><p style="font-size:12pt;font-family:helvetica,arial,sans-serif;color:#333333;" class="default-style"><br></p><p style="font-size:12pt;font-family:helvetica,arial,sans-serif;color:#333333;" class="default-style">Doesn't really matter, I suppose, since I wear a respirator, goggles, and (tomorrow) a San Francisco Giants baseball cap. <br></p><p style="font-size:12pt;font-family:helvetica,arial,sans-serif;color:#333333;" class="default-style"><br></p><p style="font-size:12pt;font-family:helvetica,arial,sans-serif;color:#333333;" class="default-style">But isn't that a bit of a contradiction?<br></p><p style="font-size:12pt;font-family:helvetica,arial,sans-serif;color:#333333;" class="default-style"><br></p><p style="font-size:12pt;font-family:helvetica,arial,sans-serif;color:#333333;" class="default-style">Terry Smith, '59 TR3A TS 58667<br></p><p style="font-size:12pt;font-family:helvetica,arial,sans-serif;color:#333333;" class="default-style">New Hampshire<br></p><p style="font-size:12pt;font-family:helvetica,arial,sans-serif;color:#333333;" class="default-style"><br></p><p style="font-size:12pt;font-family:helvetica,arial,sans-serif;color:#333333;" class="default-style"><br></p></body></html>
