I just replace the head gasket on my 2004 Nissan Altima 2.5L. I saw video where Ford Tech Makuloco recommended the 125 grit disc for Al heads. He was right, as it works well but you have to be careful to not have too much speed or move too slowly. Much as this was also reinforced the reviews on Amazon. Overall it's a decent product and makes quick work of removing gasket material. I will continue to use it, although I would recommend it more on steel than aluminum, unless I found a finer grit disc.

This little brush works awesome! I start off with CRC gasket remover sitting for 15 mins, followed by a gasket scraper, and finish off with the roloc pad and wow! Had to take pictures of my project. I'm doing original head gaskets on a 1997 suburban 350 small block, and I need something that I could use with the engine in the vehicle. Scotch Brite pads are great IF the engine is fully disassembled on the stand. Many shops don't allow the use of scotch Brite pads due to aluminum oxide destroying engine bearings, and other critical tolerance parts. I ordered this and yes it takes more time and I'm using a cordless power drill BUT the CRC gasket remover spray can be used in conjunction with this directly! This speeds up the process of the gasket removal by 10X compared to using the roloc alone. I haven't tried carburetor cleaner with it yet, but the gasket remover spray works fine with it (just costs more than good ole' carb cleaner). Gonna buy more to prevent washed out bearings, aluminum oxide pads are thing of the past. Just be careful installing onto mandrel as it is 100% plastic, and a little hard to screw on.

Was watching a YouTube video of a guy using this brush to clean cylinder heads and engine block surfaces, so I bought it as I was in the middle of a similar project. I just finished doing a top end job on my Ford 302 and it cleaned up all the gasket mating surfaces with ease, speed, and didn't ruin the material of the cast iron heads and block. After cleaning every mating surface with it, it has held up really well with plenty of life left. As you can see in the picture, the right half is not brushed and the left half is brushed. Quite the difference with very little effort.

These work great but the listing is worded that you think you'll get 2 but its only one, its size "2"Ive used these to clean up old gasket material on a iron block, aluminum heads, valve covers, etc. Wont remove too much material like a regular rolac disk but you still have to be careful and not stay in one spot or it could remove some material. After cleaning up the surfaces on 1 engine you'll probably want to replace it

Cleans aluminum head deposits - like gasket stains, etc., without damaging the head. Used with high speed compressed air polisher/die grinder.

I use this color to strip old gaskets from flanges or blocks and heads.These leave small scratches in aluminum, so I make a couple passes with emory cloth and the surface is good to go. Make sure you clean/rinse what you are working on because this will leave powder of itself when used.

For the price this is an amazing tool to have. I used it on my aluminum block engine to clean the old gaskets residue. It might take some passes but take your time. It doesn't eat the block but don't leave it in one spot for too long while cleaning. You can use it with your drill!!! Well worth the money! Even after cleaning then engine block and heads and everywhere where there was old gasket residues including front and back plates, it still looked like it had some more life out of one bit - look at pictures of the aftermath. Make sure it is a genuine one.

I've used these several times to clean piston heads during valve jobs. With lubrication, they work well and have not yet scratched the aluminum.

Utterly useless. Melted immediately upon use. Seriously, how are you selling this?!

These roloc bristle brushes are the best product for resurfacing. They are fast, easy to use and don't leave damage. (Also this listing is real roloc watch out for fake ones)

Used this on stuck on gasket on motorcycle parts...way better than scraping and gouging gasket surfaces. Get some. Don't forget 2 inch chuck pads.
