Great for amateurs

This really is the best thing since sanding blocks, this allows you to actually get a perfect compound curve repaired like a pro.

For sure! We're glad you like the blocks! Thank you for supporting our small business!

Block review

The block work's great,but I would like to know what to use to get the sticky build up off it. Thanks Greg

Awesome Blocks

Been using the 18 flex, 24 stiff for about a week now. Easy to use, hand comfort is awesome. I'll be buying other sizes to use.
