Motor Guard - Roller-Block Precision Wet Sanding Block (RL-1), One Size

Context:Wet and dry sanding on 2005 Dodge Ram fender. There is barely a flat surface on it.Pro:It did not soak up water when wet sanding.Paper did not bind or slip off of the block (no adhesives used)Thin enough to feel contours but thick enough to hold a consistent sanding surface.Cons:None really. Just be sure you know what it is for.Maybe a little thin.......Maybe not.Notes:This is better described as a contour block. It is working great in the contours of the fender I am working on but a thicker block would probably do just as well and be more comfortable for the amount of sanding I am doing. They have a couple of "Big Block" options I plan on getting before moving on to the next body panel.

So this is a great block for sanding both flat and curved surfaces, and I really recommend purchasing it if you do any wet sanding. I would purchase it again.BUT, I can't help thinking that if I knew where to buy this type of foam, I could cut at least 5 of these for $10 rather than just 1. So, rather than buying more now, I'm trying to find a foam that's similar to it from McMaster or someone. There's not a lot of "engineering" that went into this block—it's just foam rubber—though I do notice that this block appears to be made of 2 layers of foam (black and gray), but I'm not sure if they are different density. It appears the bottom half _may_ be slightly less dense than the top half, but not sure how required that would be.I think I've even seen a similar type of foam used for packaging some products. (Things that come in those fancy durable boxes, that are sometimes hinged—like smart phones, vaporizers, airbrushes—anything they're trying to give a "luxury" feel—sometimes come with a piece of it cut out to fit the product. Keeping my eye out! Until then, go for this, I guess!

Very durable sanding block for wet or dry use. Would buy again.

Exactly what I wanted & good price. I used this to wet sand a tailgate with 1500 grit sandpaper.

Perfect block for wet sanding any surface that has some contour to it.

First off, the product is fine. My low review is for the misleading or rather under-informative product description. Not once anywhere in this description does it state that is not for use with adhesive paper. I pulled the product out of the packaging, applied a strip of 3M 180 Stik-it, did my thing, went to refresh the strip and tore the whole pad to pieces. Effectively made it one time use all because nothing ever mentioned it's intended applications do not include sticky paper.To reiterate: the product is just fine, it cut beautifully during is first use. Even pressure, contoured like a dream, not a single problem until I discovered it wasn't meant for sticky paper. This review is more for the product description than anything. I'll be buying another one, but it's going to be for wet sanding or non stick dry paper only.

Flexible, good for sanding primer and paint over curved surfaces on automobiles.

Great product

Producto muy bueno en durabilidad y acabado

not too bad

Painted my Harley and used this block in every step.

Love this pad, I use it for sanding contoured automotive stuff all the time. Will get a larger one next time

It looks like I misunderstood this products intentions. When I received it, I realized it was just a piece of foam. A very expensive piece of foam. When I ordered it I was thinking it was an actual sanding block, meaning you used it to sand with as the item itself had some abrasive qualities to it. I understood that I still needed sandpaper with it, but this "special" piece of foam somehow made it "better" by being abrasive and holding onto the sandpaper in some special way, At least I think that's what I was thinking. I don't know any more as it has been quite some time since I have been this disappointed in an item.This item is simply a piece of foam with some self-advertising written across it, but has no additional sanding qualities about. Other than being some kind of thick, yet somewhat flexible foam pad about a quarter inch thick. It does not hold onto your sandpaper. In fact, it does not do anything other than being something to wrap your sandpaper around, and it does not even do that very well. Your wet sandpaper still slips around the foam in an annoying fashion so you're never certain of the precision of your sanding.I did use it...for less than 2 minutes. After the first 10 seconds I was thinking "why on earth would anyone need this absurdly overpriced piece of foam to wet sand with? How is this any better than the rubber sanding block I already own that actually HOLDS onto the sandpaper? Why did I pay almost 20 bucks for this?"The answers to my questions are obvious. Question 1: I cannot see any reason why anyone would need this item. And 2, It's not any better. Matter of fact it's worse than the rubber sanding block which is probably less than half the price, easier to hold onto, and actually grips the sandpaper for you. And finally, to answer #3 - I'm still baffled at my own stupidity periodically. If this was $4.99 I probably would have kept it as a reminder that I paid $4.99 for a piece of useless foam and that I am an idiot for doing so. But nope. For $20 it's going back to JB for this weeks yacht remodeling crew to use.This is one of those items that some marketing genius thought up and convinced enough gullible people that they actually really really need this. The guy (or gal) is probably a millionaire by now too.If you bought this and found it useful, well, all the power to you. I'm glad you did. Sincerely, I am.I personally found it useless and I'm quite embarrassed that I even bought it in the first place.
