Review: Excellent Product, NOT a miracle worker - Short review: This product works well if you don't expect a miracle and thoroughly remove as much loose rust as you can before applying Extend Rust Neutralizer. Long review: The biggest task I've used this on is for my vehicle's calipers which were rusty to the point where I could flake pieces off. I took them off and used the process of electrolysis to remove most of the rust and scrubbed them vigorously until the calipers looked mostly like shiny bare steel. I then painted the calipers with Extend Rust Neutralizer (which dries on rust as a black finish) and then coated them with caliper paint. The key to this product is removing as much rust as you can! If you can get down to bare metal as best as possible then use this product I believe it will work and last for a long time. It can only penetrate into the top most layer of rust. It will NOT convert flaky rusted apart things into like new shape. Also I had to buy a reman. caliper as well since it was too far gone, I did not scrub it down to bare metal as it was painted already, so I just painted it with the matching caliper paint I already had. In about 1 month the paint on that caliper had mostly come off leaving an orange rusty finish, the calipers I cleaned well and used Extend on are still rust free after over a year. I've also used this to paint over rust spots on vehicles with success in the fact that the rust hasn't spread further. By sealing the rust off from the air it has prevented the rust from getting more water & oxygen which has greatly reduced it's ability to spread. While I understand the rust is still spreading the speed is greatly inhibited. I would absolutely recommend this product as a base coat to put down under say a rust inhibiting primer, then paint and/or clearcoat. I believe that the product turning black is an actual function of it converting the rust. When it's painted on a non metallic surface it dries a semi translucent white color, but when applied to a steel with rust it dries black.
Review: This product works well but is very slow acting. - I’m a HUUUUGE fan of Locktite products. Their bottom line and my retirement account have similar amounts of my money involved... my machine shop could not function without the reliability of Loctite products. Okay, enough of the groupie-sycophant 🤤 drooling! I purchased this product to address some surface rust showing on a blued rifle barrel end. It is the rough Aluminum Oxide black finish that is NEVER supposed to rust! 😂 I tried this first on a tin plated steel surface to see how thoroughly and quickly it works. It is a tan colored suspension that heavily coats the surface and dries slowly. After 30 minutes I wiped away the powder residue and there was evidence of darkening but the rust remained. I reapplied and let it set for 14 hours. The rusted area had darkened to deep blue/ black color and every evidence of rust wiped off with the residue leaving a perfectly smooth rust free black shiny surface. Next comes the outer surface of the rifle barrel. There is nothing in this which can penetrate more than 30/Millionths into the surface or effect the strength or temper of the metal. It is utterly safe for this application. I would NOT recommend it’s use INSIDE the barrel of any weapon or any surface exposed to high explosive pressures without first conducting a metallurgical analysis to determine alloy and existing static strengths and resistance to these chemicals. I use this product often in protecting mild steel surfaces and welds to tool steel where it will remain exposed to weather. It is truly an amazing product. As long as you don’t mind waiting a bit for it’s full effect. The protective surface lasts about a year on ductile cast iron wheels where I use it annually along with bearing grease to preserve and maintain heavy duty machined cast iron barn door rollers and rail. It was sent to me within 2 days of ordering. This seller is fast, affordable and carries a great product.

## Questions & Answers

**Q: how is this different from a rust converter**
A: It is not different.  It IS rust converter.  Extend is the Loctite brand name for its rust converter.

**Q: My frame has tiny spotted/speckled rust areas. Will this product still adhere okay with paint inbetween the many rust spots?**
A: It worked fine for me and I had a similar situation. If the area is not too big, you could just sandpaper it, then put the loctite stuff on and paint it later.

**Q: The description says it's an aerosol, but the picture looks like a bottle. Which is it?**
A: Judith,The Locktite product that I have purchased are the small bottles with applicator brushes for delicate work.  I have no experience with the 235285 product.  I would say just by looking at the picture that it is not an aerosol.  I hope you find a definite answer from someone who has actually purchased the Henkel 235285 product.  Good luck!  The product which I use (small bottle with applicator brush does a good job.

**Q: I had some spill on some copper. Will it harm copper?**
A: MAY DISCOLOR IT—THATS IT

### ⭐⭐⭐⭐⭐ Easy to apply and effective
*by J***R on October 30, 2025*

This really works. It’s easy to apply. I applied it to surface rust on my truck and it turned it black and sealed it. After several rain events it shows no deteriorating.
