What penetrant do you use on rusty bolts? - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

vin63 · 01-14-2014, 01:22 PM

If there's a lot of rust/corrosion, I use Kroil. It can leave a strong odor. Otherwise, I use Gibbs Brand on just about everything else (drag cars, hot rods, etc.), including using it as my primary CLP on my guns - its the only CLP I use on my M4s and shotguns.

Better as a water displacing ("WD") oil than a penetrating oil.

I guess I'm cheap. Heat up then stick it with a candle. Let the wax penetrate then off she comes!

pwdcougar · 04-13-2014, 02:49 PM

PBlaster. Have a VW bug in the shop now that has been sitting outside since 1986. All the brake lines and bleeders came loose no problems!

Kroil Just don't get it on yourself works awesome.... Damn Cat loves the stuff I cant get rid of the little bugger when i spray it lol.

In The Ten Ring · 04-25-2014, 12:38 AM

ZEP 45. I used to sell the stuff and it works pretty well. Twister (also by ZEP) is another good one.

kmfb · 06-13-2014, 12:13 AM

aerokroil all the way! The local Napa stores carry it around here. I keep 2 cans in my tool box all the time

I tried this awile ago on some rusty bumper bolts, just to see if it works....To my suprise.....the wax works great ! Heat & pb blaster work also.

hd74 · 07-16-2014, 06:35 PM

PB Blaster works and cheap compared to some others

Tinkermc · 07-16-2014, 08:22 PM

Funny you should ask, today I started a resto on a 71 Long Box for a long time customer. Trying to take apart the bed I found all bolts were rusted well. I used PBlaster on them and I can now say they all came out. So I must say PB is the bomb.

X2…I've used Gibbs Brand since the '80s for my racing and fabrication, and it's the only CLP I use on my rifles. It works on about 80% of the rusty fasteners. The other 20% I use Kroil from Kano Labs.

motornut · 08-07-2014, 09:45 PM

liquid wrench or PB works for me

Nin92 · 08-09-2014, 04:00 AM

+1 for PB Blaster.

Where can I buy Kroil?

**truckster** · 10-11-2014, 03:19 PM

If you do a search, someone posted an actual test of a bunch of different penetrants with the torque required to break loose rusty bolts/nuts. The clear winner was acetone/ATF. I didn't really believe it, until I mixed some up. It really does work well. It's not as convenient as the spray cans, but I keep some in a plastic spray bottle. Make sure you shake it up before you use it.
