can it used on screws to prevent rusting?

The product chemically reacts with rust to turn it to a priner. You still need to paint over it after. If the screws are not rusted there is no reaction chemically. So it would not protect.

No, it's primary purpose is to convert rust to a black substance than can be sanded. Just oil your chain.

you can spray it on the metal before rusts but will not take rust off. It will still flake.

Although I've never tried it on metal, it should work fine because this wipe-on poly is oil-based and not water-based. A water-based wipe-on poly will cause the metal to rust, but an oil-based one shouldn't.

Sorry can't help you ...but stainless is not suppose to rust ?.. unless its around salt water etc ...? and even then, depending on what type of stainless it is .. I have not used it in that application so I can't really say. Its is very durable finish ( if done I would suggest only spraying it and doing multiple coats). At least 3

I would not use it on stainless steel, it would scratch it! If you read the directions it tells you.

it says it is good for all metals, so I think it could be used on stainless. Bust a stainless cleaner is likely cheaper.

It's just a screw. If it's going outside you don't want it to rust. I put mine through aluminum siding. But if you need sheet metal, why not?

It's not something I would use alone it would have to be cleaned up some and maybe even filled with a heavy primer. the key behind this produce is it stops the rust through a chemical reaction. This chemical reaction may cause damage to areas with paint, Its a great product but follow the directions closely.

I do not know. I have used this product only on ferrous metals and have not tried it on any stainless steel alloys. This product will remove rust, but it can not keep it from coming back. The area where the rust is removed will look clean but needs to be sealed to minimize the return of oxidation, maybe a high temp cooking oil thinly applied to the effected area could serve this purpose. good luck.

This stuff is great for bonding/preventing rust. I have used it for more than 40 years. When you applied it to rust, it will bond the rust to the metal and turn black. Now with your question, I presume we are talking about steel doors, right? First sand the loose rust off, apply Ospho directly to the remaining rust, let it sit till it becomes black. If you want a smooth door, sand again, apply sopho again, it will act as a primer. When dry, paint to taste.

As long as it stays on, yes. If it cracks off, t may not. Stainless is not suppose to rust at all. That's why its STAINLESS....

I use it on my stainless sink hardware and pots. But there is an Astonish stainless steel cleaner.

No, It is only effective on Brass! If you spray it on stainless steel it will dry to a milky appearance.

I used it to repair a 2 inch slice in and aluminum boat. It worked perfect for that endeavor. I see no rust on the repair and there was no rust on the damaged part of boat.

I have not tried this but if the screw has not too large a diameter, I do not see why not.

Yes... It is the water that initially breaks down the coating on the dish rack and yes... Once that coating is fully compromised, it will rust. The chemicals and other properties of the water will just eat away at it over time, however, the best solution has already been stated. Buy a can of Rustoleum Clear Coat or any regular Polyurethane that will adhere to the coating, whether that be chrome or plastic, and spray it all over the rack... And don't forget to remove the plastic utensil holder, if there is one, and DO spray the feet. Two applications are best so it will take a couple of days to paint, dry and recoat... Then to dry, fully, for use. Yes... It is the water that initially breaks down the coating on the dish rack and yes... Once that coating is fully compromised, it will rust.
