I used your<span></span> suggestion Mike and it worked great! I had to go stronger with the muriatic, let it sit about 15 min and a strato grit brush with 200 lbs of weight worked great.<div><br></div><div>Thank you!</div>

Thanks mike. I had &nbsp;previously&nbsp;tried a nylo grit with no results. Straight hydrochloric&nbsp;acid seemed to loosen it some. Maybe I could try the strata after allowing hitting it with acid.<u></u><u></u></p><div><p class="MsoNormal">
