Board was great. Bought all of the 32 inch boards. From mild to stiff in flexibility

Boards are excellent. Was skeptical at first after buying other boards that were lawn edging with a piece of plastic glued to them. These are awesome, work well and are versatile. The different stiffness of the boards per cuts are perfect. Durablocks were my go to, and still have a purpose but these are the number one go to block in my restoration shop.

Very comfortable instead of duct tape handles

I’ve tried of a lot of different sanding blocks in my days trying to make cars straight as an arrow and yes to me, it’s the most challenging part of the process, but also the most rewarding, I was amazed of how fast they cut through mud and finding low spots from other competitor blocks the 18 rigid and flex are my go to for flat doors. And the plus side is my hands are not cramped from holding a duck taped handle. These are great.!!

Great Block for the price!

Side Panel, Door Panels, Quarters Panels heck a great all around block for straightening work or panel to panel work. I find this block nice for areas ahead or behind wheel well openings and over-all smoothness and matching. Once the majority is close I'll switch it out for the longest block to cover the largest areas for that over-all perfect flat panel matching. I will no doubt use it much more on the interior, ceiling and rear shelf, inner door panels, floor and center tunnel as well as half of the dashboard. The front and rear sections underneath the car will benefit greatly from this block as well.

Bought this block with the 18” set. I use all three versions of the 18” blocks regularly. These are the best blocks I’ve used. I recommend them to everyone I talk to.
