I have been looking for something like this for awhile and finally found these. I am very pleased with my purchase. I actually just had to sand a small run out of a cab corner this morning and these blocks worked perfectly to get it flat.
I’m a novice/hobby body guy but have been trying to get panels straight with hard foam blocks with minimal success. This will hopefully make my results appear like I know what I’m doing.
I bought several of the Linear Ultra Flex Blocks and tried the 24" on a door that I had just finished (I thought). When I re blocked it I was amazed at how it showed several spots that were low and still needed work.
