Permatex 99070 The Right Stuff Gasket Maker, 5 oz. - 2 Pack with Caulking Gun

ive used it on transmission pan and it sealed it very good

What else is there to say. I use it for repairing all sorts of items. Great product. I always keep some on hand. PS, it is dishwasher safe.

If you’re a DIYer working on your car or small engine, this stuff is a game changer. I used it to seal a valve cover and it worked perfectly—no leaks and no need to recheck. It sets up fast and holds tight. The caulking gun makes it way easier to apply evenly compared to the little tubes. You get two cans, so it’ll last a while. Definitely a must-have in the garage.

good value compared to local jobber

I purchased this Permatex® 99070 The Right Stuff® Gasket Maker, 5 oz. - 2 Pack with Caulking Gun from Amazon in February 2018 for the purpose of fixing the dashboard in my 2008 Mercury Milan that was bulging around the passenger air bag trim cover. Basically, the original manufacturer's adhesive located beneath that area had lost its effectiveness after several years (a commonly-reported issue by Mercury Milan and Ford Fusion owners). Rather than paying a dealer or independent auto shop to fix that issue, it was suggested to me by an experienced auto technician, who frequently performs this same type of repair, that I simply do what he does and apply this Right Stuff® Gasket Maker 33694 (black colored caulk gun type) adhesive with the included application gun (or equivalent) to the underside of the warped section of the dash board, after first removing the air bag. I did just that and the fix worked flawlessly. No dashboard bulging has returned after several years later. The reason that this adhesive product was recommended to me, versus another sort of stronger automobile adhesive (e.g., 3M), is because the dashboard area can become very hot from sunlight and so the adhesive must be able to withstand excessively high temperatures which this product is perfectly capable of doing. For this specific application, at least, I have been completely satisfied with this product. I like the caulking gun that’s included with this bundle. While a regular caulking gun can also be used with these smaller 5 oz. tubes, I specifically needed this shorter gun to facilitate working in the confined space between by car’s dash and windshield… which it did brilliantly. The gray frame measures 8 inches long and that includes the 6-inch length of the cradle plus the 2-inch long top-most portion of the handle attached to the end of the cradle. The fixed handle portion measures 6-1/4 inches long from top to bottom. The 1/4” diameter push rod measures 9 inches long plus an additional 1/2-inch for the bent end portion of it. These short 5 oz. tubes of Right Stuff® black one minute gasket measure 5-1/4“ long and fit nicely into this gun’s 6-inch long cradle, as shown in my attached photo. Similarly-short tubes of RTV/sealants should work equally well in it. For my own personal and occasional shop use, I find its overall quality to be satisfactory… at least for an imported (i.e., Made in China) tool. While true that it’s constructed of a thinner gauge steel and is not really what one might deem to be a heavy-duty tool, the gun still manages to have a pretty “solid” feel to it and does not necessarily feel cheap or flimsy. I would classify it more as a medium-duty type tool. The push rod seems pretty beefy/sturdy and is notched on its one side to facilitate the gun’s smooth ratcheting drive mechanism. I like that the circular metal plate attached to the end of the push rod can be easily removed, presumably to clean it, by simply loosening its hex nut, although I haven't found any reason to do that yet. A handy spout cutter, measuring 3/8” in diameter, is included on the fixed handgrip portion and operated by squeezing the trigger grip which has a sharpened edge behind the spout cutter hole for the purpose of cutting the tip. Attached to the underside of the cradle is a caulk tube seal puncher rod/wire, measuring 3-1/4” long, used for poking holes in the foil seal of the tube. The gray painted finish on my gun seems to have been applied neatly by the manufacturer and has been durable and held up well through my occasional use of the gun during the past three years. No markings whatsoever are present on the gun, except for three somewhat cheesy-looking model #, “SPOUT CUTTER” and “MADE IN CHINA” labels that have been affixed to it; I presume this is a cost-cutting measure by the manufacturer to eliminate the step of actually stamping that information onto the tool itself. Some reviewers have noted that the ratcheting drive systems of this gun did not hold up well or even broke during prolonged daily use in a professional shop. While it’s a decent enough tool for home or light/moderate usage, I can certainly see where this gun could likely wear to the point of eventually failing to ratchet any longer under consistently heavy usage. But this gun is still fairly affordable enough and a good enough overall value that I can’t see why a professional shop or heavy user wouldn’t mind having to replace this gun every so often, if necessary, since it can be purchased separately here on Amazon.

Best product

The go to gasket maker nothing is better tried them all

I have used this several times now and both the sealant and gun are excellent. The gun has a tip which extends past the sealant cartridge whilst allows you to keep a good bead at the proper angle. It also ratchets well and has a blade in the handle for snipping the end of new cartridges. Very useful. The sealant can be used anywhere under 450F and that is not exposed to gasoline. I have used this to seal a couple of oil pans and some water pumps. Directions say that parts must be together within 5 minutes, but I find that you can go closer to 7-8 before you have to start panicking. If you have your tools lined up and ready to go then that is not an obstacle for something as large as an oil pan. The seal cures very fast and can be put straight in to service as per the documentation, though I would wait an hour or two to be sure. The best advantage of The Right Stuff over other silicone sealants is that is does NOT need to be Re-Torqued after being applied. Not after 30 minutes, not after an hour, not after a day. Torque the bolts when you install the part and no more fuss.

Muy bien
