Guest EDBS0 Posted September 8, 2001 Share Posted September 8, 2001 Have some stubborn bolts. What is the best penetrating oil there is. For the most part I use Rust Check Rust Inhibitor. I know it is supposed to stop rust but it has an incredible capilliary action. Is there anything better?<P>Regards, Robert Link to comment Share on other sites More sharing options...
Guest Posted September 9, 2001 Share Posted September 9, 2001 I hear that Kroil is good stuff. Link to comment Share on other sites More sharing options...
Guest COMPACTBC Posted September 9, 2001 Share Posted September 9, 2001 I've had good results with Prolong, even though its not advertised for this purpose, it really works good. Link to comment Share on other sites More sharing options...
YellowLark Posted September 9, 2001 Share Posted September 9, 2001 How about PB Blaster?<P>I heard really good things about it on several car sites last year, and have been using it on old boat motors and car parts with very good results - no more broken bolts! You have to let it sit for several hours for maximum effect. Link to comment Share on other sites More sharing options...
Guest Posted September 9, 2001 Share Posted September 9, 2001 Kroil gets my vote too. If it gets really bad and concerns a part that can sustain some heat, like exhaust manifold nuts/bolts or suspension fasteners, I apply some heat with oxy/acetylene, quench with water...if that doesn't work I add the Kroil at the end.

86 2dr.ltd Posted September 10, 2001 Share Posted September 10, 2001 I try to wire brush the exposed threads with a small drill wheel brush and then use heat according to what the piece or part can take.Ive never had any luck with miracle sprays and no longer waste shelf space on them.A couple drops of oil will help on the ones that are just coming hard.Also working them in and out slowly can help keep from breaking.A heated bolt or nut will not have its original temper.

Guest Posted September 10, 2001 Share Posted September 10, 2001 the new Formula Liquid wrench in the Blue can works really great, But honestly By far the best i have ever seen is a British Product called GT-85 spray lube. we actually used it to remove a Center Bolt seized in a Crankshaft all you had to do was spray it on and hit the bolt several tims with a hammer and leave it alone for like 30 mins. it actually came out and you could see thet depth of penetration into the threads. <BR> when reintsalling any Bolts i think may lock up i like to put a small bit of Copper anti-seize on them.

Guest Posted September 11, 2001 Share Posted September 11, 2001 Have any of you ever tried anything called Never-seize? I use it all the time. I'm not sure if you've ever heard of it before though, as it's only mostly used in industries... Link to comment Share on other sites More sharing options...
Guest Daves69 Posted September 12, 2001 Share Posted September 12, 2001 Never Seize is great to prevent corrosion when assembling fasteners. I work as an aircraft mechanic and we use this stuff to prevent corroded fasteners. Kroil is one of the best penetrants I have used. Brush the loose rust from the bolts first then spray let it sit for a while to let it penetrate, add some heat to help with the capilary action. Remember if the bo;t breaks it probably needed replacing. Link to comment Share on other sites More sharing options...
Guest Posted September 13, 2001 Share Posted September 13, 2001 yep, I mentioned that because my dad is the supervisor of one of the plants that makes never-seize products. It's made by a company named Bostik. Link to comment Share on other sites More sharing options...
