I know that in a regular repair i has to use the method of pressure and then vacuum but when repairing long crack i set up the pressure cycle let the resin run down a crack until it reach the mini bulls eyes created at the end of the crack.what i want to know is,do i have to do a vacuum cycle like in a regular repair?can i use a sewer machine neddle to create a bullseyes i the hole at the end of the crack or is to sharp for that?
