I was impressed by the quality and price of the filter housing and replacement filters. Works as advertised!

best block i ever used!! cuts down on time as well as sandpaper. with this block i find you will use more of the sandpaper surface
than a foam block.and now i have the storage rack handy to have the blocks on the wall...i also use your wet sanding paper with Linear Blocks
for a much flatter finish what a nice product!!
thanks Tim Smittys Hot Rods

Seem incredible I just have to get used to them but high quality I'm very happy with my order

It took me some time to pull the trigger on the 12 inch 3 piece set….first time using them and absolutely amazing…I have been a body tech 42 years and I wish I had these years ago. They sand much faster, it’s almost like they cut…..and it takes the guess work out of sanding. I will be getting more from Linear

Complete spreader set to take care of any body filler applications.

Your products provide laser straight body work.

They work fine, the edges are a bit sharp, might sand them down. Over all great product.

I've been doing some very nice curves on a very old fiberglass monocoque Lotus Elite Type 14 with custom streamlining aerodynamics. The 32" Ultra Flex Block is absolutely phenomenal in perfecting all those curved and reversed curved panels! In the lesser curved areas like panel to panel with the door and boot lid I start with several sized Flex Blocks and 1" rounds and true the form very quickly around about 80% of the car. Then I go for the 32" Ultra Flex Block to easily dial the whole car into perfection! This after doing years of repairs on stress cracks, normal bodywork and creating NACA Ducts, flush fit front and rear windscreens, recessed headlamps with headlight cover fitments and directional signal lamps as well as a whole "Costin Nose" refinements as well as a double reverse angle Kamm tail construction and body seams, makes all my hand sanding to bring it all together so much easier with unbeatable laser straight curves you just can't achieve with anything else! ***Please pay attention to promotions, as I also received a FREE Fisheye Filter with my purchase! Thank You Linear Blocking Tools for that wonderful Christmas / New Years = BONUS!! (Photos are for reference only - Always use a respirator!!)

Just another tool to get you a little better we haven’t got yours yet you’re missing out

If you were thinking of getting these highly recommended can’t go is wrong with these Not only a great Friday. Good people to work with.

Absolutely amazing blocks Colten always puts out great products and I couldn't be happier with the results.

Been in the collision industry for 33 yrs and these by far are the best blocks I’ve ever used. A definite game changer when it comes to straighten panels.

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.

I used these blocks for flattening out my clear and I also used them to final block. They are super straight. They found a few places my other blocks missed but blocked out. Highly recommend them. I liked them so well I ordered a set of regular blocks.

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.
