Collection: Hydrographic

Even if your familiar with metal prep and corrosion protection, this video is worth watching! Your not going to find professional information and explanation like this on You Tube.

The foam allows you to have grip while holding it to the panel. Works much better than an alternative that I used to use in the past. Highly recommend these along with all the other blocks they offer.

My work involves much sculpting and very sharp, reverse and double compound curvatures. Much like those who do artwork or fiberglass molds for kit-car type situations to perfection. In creating aerodynamic principles to exotic European body styles, I had made a suggestion to Colten to expand in this area of a more flexible acrylic block which is more akin to more precise curves and varying curves for this type of work and creativity. These are a great answer to what I needed as with many exotic European cars you will never find a spot that isn't curved and needs more hand control and twisting options from a very slight tight curve into much larger radius areas but still with enough strength to even out the transition of the blended areas or reverse / double compound curvature areas. These blocks are prefect for this as well as having a soft side which is great for after getting your body formed perfected and painted the softer side is perfect for any color sanding or final wet sanding of clear to follow the perfected bodywork you've already created whether on a body or in a mold to produce multiple parts these are a "Must-Have" for those with a more specific professional need as well as those who just want a perfect clear-coat wet sanding block for that last very fine block before polish. I am thrilled with these as I know you will be too if you have the strive for perfection. A grand slam for Linear and I hope to see some other suggestions I have made for more specified tools will also be revealed in time with the same quality and care that only Linear Blocking Tools can give! Thank you for helping our vast industry with even more specific tools for the trade!

These blocks are amazing!
I can close my eyes and just sand away with these blocks and everything comes out flat 😂 .
After using them for a week I realize they save me a lot time and effort.
These sand blocks are a game changer....
I simply love them

works very well will buy more very very happy thank you

Great product very happy

Love these blocks, great quality

As always a great product

One I will get this.

Nice blocks a little pricey but are quality made.

Only used the super flexible one so far on a Squarebody roof that I had to skim and absolutely love it! Amazing block and wish I had them years ago.

Great service department! Thanks for the replacement block

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.

Product arrived earlier than expected and customer service at linear blocking was fantastic

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.
