I'm Mexican and I need your help for repair long cracks. The last year I bought a EZK-121 12v Double Bridge Windshield Repair Kit.
So, I need to know if is necessary to use a crack expander to repair any long crack?
Can I make a crack expander for myself or have to buy a manufactured by any company.
Other question: for Long cracks which is the form step by step to repair them?
Thank's to everybody forum!!
Sorry, but my english it too poor!!
