        Hi,

        I have a set of frames for the 3 1/2 guage LILLA that i am about to treat with something to stop them rusting in the garage,I have sandblasted them clean and was wondering how effective a black oxide solution would be via a spray gun,Any ideas or experiance of this ?? least then i could black the other propriotory components to match…..

        or am i better priming with matt black paint,any recommendations for a type of primer?

        Thanks for your answers…..Deltic007

            Upol Acid Etch #8 is fine, but if you want to do other than have a short term cover, it needs to be overcoated with a stronger primer or top coat

              Other options are wax candle rubbed all over warmed up and smeered around to get full coverage. Very nice to handle. Or in summer waxyoil diluted with white spirit and hung in the sun to dry off the pong. Not so nice to handle.

              Don't use any kind if car polish or furniture polish though as they contain silicone.

                I usually treat my machine tools, steel items of workshop equipment and part completed models with Shell Ensis anti-rust oil, wiped on with a soaked rag. It seems to provide very good protection, but can easily be removed for painting with white spirit or similar solvent.

                  Just a small point that has bothered me for some time. I keep reading about not using certain products because they contain silicone. Can anybody explain what the problem is with silicone?

                    Doug, the silicon is very hard to get rid of and if you paint over it , the paint will never stay on the metal.

                    If you get it on a windscreen then you will not be able to see through it when it rains. I t acxts basically as a repellant.

                    Also if it gets into a thread it can sieze the screws you put in.

                      I think you guys did not read the full problem/questions ,I want to use paint or Black oxide not any sort of anti rust oils,That would be bad news as it is very hard to get rid of completely especially in a set of frames where oil can creep round the back of things.

                      Cheers

                        If there is big general engineering works anywhere nearby or a firm of industrial platers ask them if they will phosphate the frames for you .

                        Its a common process which leaves a non damaging near zero thickness matt grey coating on steel . Rust preventing and perfect base for later painting .

                        Its a very cheap process – especially if your job goes in with a batch of theirs .

                        There are other suitable processes but the facilities are harder to find . Zinc passivation is one possibility .

                          There is another thread on this subject on a different Forum and the concensus was as long as joints are properly rivited it don't matter, recently bought a tender frame from fleamarket rusted to hell when taken apart joints were nice and shiny. by all means give it a light coat of primer will keep you happy, but rivet up properly.

                            Deltic,

                            You have to realise that, even if you launch a thread, you don't "own" it. Sometimes the debate raises points which, though not directly relevant to you, may be of help to others in a smilar position. Get over it.

                              I'd have thought he's entitled to an answer if one is available – after all thats why he posted the question. Still one continues to see the kind of warm and friendly attitude, allied to useful and accurate advice that persuades me to visit but rarely.

                              I wouldn't worry about the oil creeping – the paint isn't going to get into places, and longer term the oil in there might do good. I'd just give it a spray of oil personally and put it aside. I've used penetrating oil on the joints for good reasons. Then come the day, give it a good scrub with a brush in hot detergent and get it warm to dry. (If you are brave enough and use gloves, then very hot caustic is pretty good, but be careful – eye protection and all that stuff) Prime and top coat ASP

                              Priming at this stage – depends on how long you want to keep it, but most primers are porous. So there is a limitation there.
