Collection: Filler Spreaders

The best blocks I’ve ever used! They get panels dead flat and have a natural comfortable feel to them! I’ll never use anything else!

I’m restoring a 68 Camaro and these blocks are unbelievable how good they work. It makes blocking out a car so much easier that it’s fun to do. I’d highly recommend these to anyone. On top of that customer service was amazing

The only issue I have with the blocks is that I wish I hadn't waited so long to buy them! I highly recommend this set and all the other block sets as well. They get the panels amazingly straight. I tested my old foam blocks vs the Linear Blocks and the difference blew my mind. Well worth the money.

Doing a body off restoration of a 67 firebird, replacing lots of rusted metal, fixing lots of dents and wavy panels. Even though I have straightened metal as good as I possibly can I am using filler and high build primer to get laser straight surfaces. Was using durablock and other
assorted foam blocks, I would sand small areas trying to achieve good enough but even when I thought I was done, the next day I would recheck the area and be disappointed, always find a ripple or high/low spot. I bought the linear starter set and WOW, 5 minutes of blocking in a prepped area and a TRUE FLAT surface is achieved!!! Thanks LINEAR!

I recently purchased this block set for the shop an the employees love them. We have five guys using them an nothing but results. These are definetly a must have if your trying to achieve perfection in reflection. #PrueittsRestoration

I really liked the video watch over three days.It helped me I've been doing sheet metal work and body work about 30 years self taught I think you guys for the affordable video and teaching.I would recommend it to any one that would like to learn.Thanks never stop teaching.Randy

Haven't used yet. Feel better in my hands then my other blocks. I got the 8 " blocks as I do motorcycle parts. Close to paint now on my current project . We'll see how they work.

I think your products and procedures are top notch; but the audio especially in the booth leaves a lot to be desired. I’m sure there must be equipment out there where the instructor can ware a microphone. Thank you for the opportunity to share and keep up the good work

these linear blocks are amazing, the best ive used to make large panels strait

Blocks work very well. Can definitely see a difference this type of block between other blocks.

I ordered one of your blocks after visiting a couple of restoration shops that use your linear sanding blocks and thought I'd give it a try. I find it incredibly comfortable and it does indeed work well for my needs as a hobbyists. Looking forward to using it with continued success.

These blocks are amazing. I blocked my 3 coats of high build with Durablocks and then ordered Linear Blocks. I was amazed on how much bodywork they revealed. These are the straightest cutting blocks you can buy!

Good quality product easy to handle. Bought some for my home project F100 now I got to have a set for my everyday job.

Although I have attempted to make my own version of this with decent results, buying this blocking tool was a good choice. For the price that seemed higher than I feel comfortable with, it is the best choice to buy the "REAL DEAL". Comfortable to use and designed very well, not sure whether the Velcro version wouldn't have been better for my use. I like the little extra cushion but that might affect the end result. I'll know better after using this block for a while yet on a few jobs.

Best blocks I’ve ever bought, made the filler work process too easy! Especially in restoration, these are the tools you need to provide the results you want to give!
