444308	2006-04-06 00:44:00	No, I've seen a rusty PC before. As soon as I opened the box, the conversation went: Me: "Do you live near the sea?" User: "Yeah, why?" Me: "Is the computer kept near a window?" User: "Uh... yeah" Short answer: rust from sea spray. Don't know the answer other than keep your next PC away from any windows. :badpc: Edit: Just realised; "keep your next PC away from Windows" :D	Peterj116 (6762)

CRC 2-26 wouild be less damaging, but it would be even less useful as a rust proofing . ;) It would be possible to protect against rust of the steel parts, by completely stripping the box and painting with a [b]proper[/] anti-corrosion paint . I found "Zinc-It" pretty good . . . it's almost a cold galvanising finish . . . on welds and new holes on hot-dip galvanised structural stuff near the sea . There are other (brushing as well as aerosol) paints which give protection by converting some of the iron to phosphate . Perhaps brushing phosphoric acid onto the bare steel parts would be effective . But I don't think it would work on plated stuff . And you can't cover everything . For example, most of the external connecters (serial, USB, parallel, etc, have steel housings . The cadmium plating is shiny . It's not rustproof . The salt gets everywhere . It's hygroscopic, which makes it worse when it gets on the circuit boards . Professional marine electronic stuff has more engineering put into the packaging than in the electronics .	Graham L (2)

444311	2006-04-06 03:29:00	No, I've seen a rusty PC before. So have I. But it certainly wasn't new.	pctek (84)

I can only give you as much information as I learnt when selling this stuff in an engineering/hardware store. CRC 5.56 is a rust preventative/lubricant, not suitable for circuit boards it will most likely eat the plastic and leave an oily residue (film). CRC 2.26 is a lubricant and used on electrics, which means it'll leave a film, probably best to use something like CO Contact Cleaner or Contact 2000, but the salt would cause the problems with it as it does good at preventing moisture etc, but rust will still be possible due to the salt. Electra-Clean is the more power 2.26 so it's not good for this. There's also Contact 60 which aftewards you apply Contact WL, again these all have similar results as above, there's also Plasticote, which is more a protective coating you can have on PC boards, but I don't think you want to coat it. LanoCote, although some aspects ok, it's used on Marine Electrics, usually movable parts (electric motors), however Marine 66, is used on marine electronics and is probably the better choice of this type but again, Marine gear is completely different from home computers but it does work against the salt. There's really a lot of products, that I only know a small amount of it, there catalogue is huge and they are always coming out with better products to replace some of the older ones. Best to call them and see what they can do, they have more experience with selecting the right products, and remember not every supplier stocks all their products so you might have to ask them where you nearest supplier of that particular product is.
