Rust Issues
I've just sandblasted my frame, now I'm going to begin the repair job.
After that I will have to fix the rust....I've already bought the 3 step KBS coating system for the outside of the frame, but what can I use to fix the rust inside the frame???

I think the best you can do is to spray something into the interior of the frame to neutralize the rust and then spray in a coating to prevent moisture from getting to the metal. I don't know what rust neutralizers are available in Europe, but for moisture prevention anything like a chain-saw bar oil that is paraffin-based or even motor oil sprayed into the interior of the frame will help keep moisture off the metal. Ever notice how the oily, grease-caked parts of the frame look like new underneath when you clean them off?

Thanks for the reply Rick
Ok for the first step, I will spray a rust converter inside the frame
I know that oil protect from rust, but I'd like to spray a specific product to protect the frame for new rust
Here in Italy restoration special products are often quite difficult to find so I usually buy them directly from USA, so I will be happy if someone can show me a product that can do the right job

http://www.eastwood.com is a good source for restoration supplies, including rust converters/preventers. There may be issues with shipping chemicals overseas but they would know if it is possible.
If you can't get anything else for the interior of the frame, a yearly spraying of motor oil will probably work just fine. I grew up in an area of the country where roads are salted heavily in the winter. My father told me about the oil treatment - they used to use it back in the 1930's.

I know Eastwood, I bought from them several products
My shippings from USA are usually throught cargo container so I haven't problems with hazardous materials
I was thinking about some strange solutions like polyurethane foam or gelcoat...any input?

Eastwood has a waxy rust inhibitor that is supposed to flow out and cover metal well. That would probably be all that you need. it might have to be applied every few years but that's not a big deal.
I may use the Eastwood wax-type inhibitor on my frame or plain chainsaw bar oil. The chainsaw oil has paraffin so it will stick to the metal, phosphoric acid to neutralize rust, and oil for general protection. It will probably have to be applied either annually or semi-annually but that should only be an hour's work.

Dream Bikes. We have a product here in Australia. Penetrol. It is used in the paint industry and stops rust dead in its tracks. Soaks into it and blocks off the oxygen which inturn stops oxidization. I used it on the inside of my chassis. I mixed it with turps,deoderized fish oil and applied it with a degreasing gun. For the tight spots I pushed a piece of clear hose over the nozzle . Pushed hose into tight areas and pulled trigger. Worked a treat!!

Thank you for the help guys
I agree that air circulation is important so the polyurethane foam is not a great idea
I think that draining holes are much important too and if my frame is rusted, I suppose that the stock ones didn't worked fine
So I will add more and larger draining holes
wax type products could work fine
also Penetrol seems me a good product, I will give a look if I can get it easly
