Best Penetrant Spray.

I think I have spent a small fortune I now have more cans of releasing fluid than perfume, and believe you me I think I just about every perfume under the sun I have a room dedicated just to them.

Anyhow, having recently been blighted with rusted on nuts and bolts, I have in order placed what I think is the best penetrants available in the U.K. In the good ol USA the number ones are PB Rust buster, Kroil and Liquid Wrench. Unfortunately we do not access to this so here goes.

 

1. BG In Force Penetrating Oil £15 (Expensive and availability poor, ebay or Power enhancer. (this one foams, so sticks better and creep is far better than most) but costy, very costy.

2. Loctite Freeze and Shock Release about £6 (Very hard to Source internet only I think now),

3.Bilt Hamber Ferrosol (this actually smells beautiful) I might place it in my perfume collection. £7 (bilhamber.com)

4. Rost off, and Rost of Ice by Wurth £8 (ebay)

5 Plus Gas £7 400ml getting hard to get hold of now.

6 3 in 1 Specialist Release Agent spray £8

7. WD40 Fast Release Penetrant. (not to be confused with ordinary WD40) £8 440ml

8. Gunk Liquid Wench (not to be confused with the far superior American product) £6 250ml

9. Lidl (yes Lidl maintenance spray) £4 ( this stuff is sold out almost as soon as they get it!

10 WD40 Blue Works Specialist (ebay) £8

11 WD40 ordinary £4. (this is a great cleaner, and degreaser, but alas no more than that! Plus point is everywhere has it.

 

The best stuff I have seen advocated on the net is a mixture of 50% acetone and 50% ATF fluid. However acetone attacks plastic. so a brush on method or a oil dispenser, which you will have to throw away, as most plastic or rubber parts.

 

The above list is for places you can't use heat.

There is a tool out there called a induction device. However not commonly available in the U.K. I think Ed Chinna uses it in one of the wheeler Dealer episodes.

 

As for keeping rust off and at bay,

The nominees are, Dinitrol Wax coat

Waxoyl

 

The winner Bilt Hamber Wax Oyl.

 

If you want to get rust off, if you have the part off, soak it in white vinegar, or Apple cider vinegar is better as it has a better pH value to attack rust.

To an addition I have on other forums, had responses, which would be hard to get hold of in England. these are Kroil, PB Blaster its what Eric the Car guy uses, Sea Foam Deep Creep, Liquid Wrench, and I've just found out that Maltby is purported be be the best in bizz, but that's the manufactures, claim, not mine. Other have told me that in the case of ceased fasteners, spray white vinegar daily to dissolve the rust, and then follow up by the penetrant of choice. I hope this helps people in the case of where they can't use good old Bluey, the (oxy acetylene) use in form of heat. Many of my rusty fasteners, are where heat would ruin rubber, paint, and near the petrol tank. There is a product called an induction heater, which uses Flemming's laws of Eddy currents, in heating up due to magnetic flux. These tolls are not readily available in the UK, and prohibitively expensive. But when you are faced with having to creep under the car every day and soaking in penetrant oils, it may be worth it. If anyone is working on their car, where practical use an anti seize compound on any nut an bolt you removed, where practical, and vibration is not an issue. If only I had done this as I have practically taken off every bolt and replaced them 20 years ago however the British climate, road salt and damp garages have played their part in rusting 1980's metal.

OK, so an update I managed to get a hold of a 5L can of Kano Labs Aerokroil. It cost £35 shipping £55 and HMRC charged £40 for import and VAT duties, (thieves)! Parcel force held up the shipment for 3 weeks. It took 2 days for the USA end to send it and took 3 weeks from Stanstead Airport to Coventry Customs!

 

But this is by far the best read made stuff! I did email a company in the USA called Maltby Chemicals who produce but they couldn't even be bothered to reply!
