Doing a body off restoration of a 67 firebird, replacing lots of rusted metal, fixing lots of dents and wavy panels. Even though I have straightened metal as good as I possibly can I am using filler and high build primer to get laser straight surfaces. Was using durablock and other
assorted foam blocks, I would sand small areas trying to achieve good enough but even when I thought I was done, the next day I would recheck the area and be disappointed, always find a ripple or high/low spot. I bought the linear starter set and WOW, 5 minutes of blocking in a prepped area and a TRUE FLAT surface is achieved!!! Thanks LINEAR!
