Collection: Wet SandPaper

100% Unequivocally the single best high build, true epoxy that I have ever used, I love spraying it, the adhesion to bare metal rivals anything on the market, ease of sanding makes body work and blocking actually enjoyable, not to mention only having to use one product from start to finish simplifies the entire process and saves money in my opinion. I will always recommend this product to anyone who specializes in restorations or custom paint, but even to the hobbyist this product is well worth every penny! Hands down my New favorite product!

I purchased 12” rigid and 12” ultra flex blocks and 3 different grits sticky paper 800, 1000, 1500. My biggest concern was the paper, I’ve used 3M wet dry paper and every time I’ve tried a different brand paper I’m always disappointed because the grit isn’t uniform, the Linear paper is fantastic in that regard and with the sticky back I waste less. With the blocks I have been blocking polyurethane clear to get the puddling or the waves out and I’m surprised at the difference it makes, I can see the low spots in the clear as I block. I use the ultra flex the most. The paper sticks to the blocks, I soak them in real hot water or carefully use the heat gun the wipe with 3m adhesive remover, kind of a pain but to me worth it. Customer service was prompt dealing with my package that was lost shipment. I bought the insurance, new product was shipped that day, very professional.

Loved the block

1st time using this product. I sprayed alot of primers over the years. Being a epoxy primer, I expected it to spray on thick but it wasn't. It was a nice thin smooth film. Would buy again.

Really like Linear Blocking Tools DTM primer. One kit got damaged in shipping. Colten and crew sent out another quart of L - 421 ASAP. The best DTM we have tried. Five Stars

Amazing product

On my third gallon on this lroject and plan on buying more!

Excellent product works well. Had a small issue with one and I emailed to see what to do about it and this companies customer service is absolutely the best I've ever had to the pleasure of dealing with. Highly recommend the product and should you need them, the customer service as well.

I like it

We have only been using these blocks for just 2 weeks but I can feel the difference already. I am buying and testing some of the more popular brands out there. Our restoration shop uses dozens of blocks during a repair or restoration and we are always looking for something new and innovative. So far these blocks have been living up the expectation we anticipated and we will be continuing to test them everyday.

Absolutely great blocks

This stuff is great. Sands good and smooth. The stuff goes on smooth and flat. Don't use to large of tip size as it can run easy. That was my fault. Will post another review when I do the entire car. I just did first block sand and want to do another coat to make sure its how I like it.

Great product. I had the body panels media blasted then I DA sanded with 80 grit. I had the undercarriage, firewall, etc., blasted with an aggressive media so it didn't need sanded. After cleaning everything, I thinned the epoxy mix as recommended and it laid out very nice for me. I used black in the engine bay area, grey on the body panels and mixed 20% black in with grey to get my original undercarriage color. After waiting 48 hours the finish was ultra smooth and sands great. I will continue to use it as I block out this project! Updates to follow.

Super love the blocking tools
