Rated 5 out of 5 by Anonymous june 2011, now nov 2012 SLUDGE JUST KEEPS WORKING.
I've had this sludge in my innertubes for18 mounths now, and had lots of punctures, but NOT ONCE HAVE I HAD TO STOP AND MEND ONE.I just pull out that thorn and ride on....and on....aand on...you get the message?
Some say it makes the wheel slightly heavier, but if you just feel the weight of the bottle when you get it,you will say it's not worth worrying about.
I have noticed that when you get lots of punctures on the same ride you may loose a little more air than you would like, and a couple of pumps will get the pressure back up.
But on one canal path ride (after the hedge cutter had been) i got 15 hawthorns out when back home, and my tire was still 40psi. was 50psi when i started.
I rest my case!.

Rated 5 out of 5 by Anonymous It keeps you going.
It does exactly what it says on the tin!.
I've never needed to repair a tyre in all the months i"ve used this. Many times i"ve pulled thorns out and hiss!!!, then revolve the wheel and emediatly it stops. When riding you done even know anything has hapened. On one ride i came home with 5 thorns in the tyre, and still i've not had to put a repair patch on anywhere.
In contrast, on holls, i hired a bike to ride Exmoor and got a flat on the way down, If sealant were in the tyres, i;m sure my ride would have been trouble free.

Rated 5 out of 5 by Anonymous makes the wheels abit heavy but overall you get used to it and closes all the punctures! i had the same tubes in for about 2 months (still do),GREAT PRODUCT!!

Rated 5 out of 5 by Anonymous Excellent sealant
Started using Dr. Sludge a year ago and no flats since!
Had one large puncture which it couldn't seal; patched the tube as usual and found out that Dr. Sludge had fixed three punctures which I hadn't even notice!
You should be careful while pumping the tyre, though; the sealant can escape through the valve and clog it. Happened once; had to clean the valve afterwards. Just don't inflate the tyres in valve-down position :)

Rated 1 out of 5 by Anonymous Slime is better!
For MTB's and offroad cycling sealant is a the best invention ever. I have changed tyres on many occasions and found several thorns had punctured the inner tube and slime had sealed the hole. Looking for a cheaper alternative to the green stuff I used this, just to find on the second trip out with new innertubes and sludge a normal puncture on the outer edge would seal but then blow out again. Needless to say I have returned to slime.

Rated 1 out of 5 by Anonymous More trouble than it was worth.
I got this stuff for my wifes mobility scooter (they do get punctures). She cant walk and would certainly not be able to repair a puncture. I didnt want her to get stranded so this seemed the answer. The trouble is that when I pump up the tyres every week or so, a small amount of this stuff gets into the schroeder valve and solidifies. The result is a flat tyre a few hours later - the exact thing I wanted to avoid. I then have to remove and clean all the valve inserts. I havent used it on a bike but I guess it would give the same problem.

Rated 5 out of 5 by Anonymous great
commute daily 18 miles return. No roadside puncture in two years which equates to 8,000 miles. Yes I do get punctures but these have all sealed while riding. Bike is a tourer with 700x35c tyres, used wit Shrader inner tubes. You can patch up any holes that the Dr sludge can't handle with a normal patch. Just hang the tube up to dry with the hole to the top for a couple of days and seal in the normal way. Last time I had the inner out I had 7 punctures which had all be sealed.

Réellement efficace.J'ai réparé un boyau ayant un trou(éclat de verre)de 2mm.(boyau sans chambre...)J'ai mis de la pression progressivement,en 3 jours.Quelques fuites les 2 1ers jours et ensuite,étancheité jusqu'a 9 bars.Je roule avec (c'était un boyau neuf a 60euros...Je l'ai sauvé....)
