The secret to easy long crack repair with Ultra Bond structrual adhesives is the crack opener. Take it from the Crackmaster himself, size matters with a crack-opener and the more the merrier. I usually use a minimum of two on a edge crack.
This size crack opener is used most often for long cracks. The demensions and custom made suction cups will symetrically open the crack so you can get our crack resin in the point area of a long crack easily without spreading the crack. The best from the one who invented long crack repair.
