"I used this when replacing a water pump on my 2006 Camry and so far so good."
"Upside is that it'll go gradually from the opening towards the back, so you can still use a small amount of it towards the wide end within a week or so if you use scissors to cut it open bit by bit until you find where it's not hardened."
"Great automotive gasket maker and adhesive - I probably use it more as an adhesive than making gaskets - Works either way - I consider it Permatex's Best Product - Never w/o it!"
"This is the best "glue" for plastic parts on a car."
"I use this stuff as a gasket replacement on my scooter and car."

Find Best Price at Amazon"When it came time to replace the severely leaking valve cover gasket on my 2005 Subaru Impreza WRX, everywhere I searched recommended Hondabond or the Subaru version called Fujibond. I spent over 2 hours thoroughly cleaning to be sure I didn't have to come back and do this procedure again any time soon."
"So far after 2 months I have no leaks, I also replaced my valve cover gasket but in the areas where Hondabond was required there are still no leaks."
"I tried first using the included screw-on point thing, but ditched it and just squeezed it out onto the surface, finger, etc which seemed to work much better. I squeezed some so it was hanging out of the end, then squished the cap on top of it to eliminate as much air inside as possible."
"I heard good things about Hondabond."
"This stuff right here....I dunno what to say, except that it is work like a mofo!"
"The sealant itself is fantastic, however the tube itself should be redesigned (mine burst at the end) ."
"I used this to seal my oil pan and it worked well."
"The only recommended sealant for use on Honda valve cover gaskets."

"No leaks, no drips, just pop the cap off with you teeth and dab some on the threads and then click the cap back on."
"BEst medium loctite to prevent bolts from backing out or holding them in for engine mechanical options!"
"Absolutely a game changer when it comes to keeping small delicate screws in place."
"Any mechanic or gunsmith knows this stuff is blue "gold"!!"
"Used on a screw that wouldn't stay tight on pistol grips."
"I really like this tube and more solid formula."
"The "glue stick" style applicator lets you use less product and it is far cleaner because it doesn't drip off of the bolt while you insert it into the threaded portion."
