The repro bolts I used (PO) on my 64 1/2 are now turning to a rust color. I will be replacing them with new bolts and wanted to know if soaking the new bolts in oil would help prolong this?? If it can, what type of oil would you all recommend?
Read my "Phosphating 101" first.
As for the old "rusty" bolts, I will be putting them through evaporust and reusing them on my next project so not a total loss.
Actually, it will. Evaporust removes rust - period. I does not provide protection to the steel. After two weeks in semi-arid California, new rust appears on previously dipped in Evaorust parts. It's less elapsed time for more humid areas. Coating them with oil without any other surface preparation seems to seal the moisture in.
i use plain old WD-40. applied periodically. works for me.
After bead blasting and phosphating - yes.
I use T9 Boeshield it seems to work better for me then regular oil ,WD40 ,etc.
I've seen little difference, except Boeshield is more expensive. When I phosphate hood hinges and latches, I flush the moving parts, joints, pivots, etc, with WD-40 until it runs clear.
FYI you might go over the bolts with a rust tinge with some eagle one chrome wheel cleaner. It has a foaming mild acid as a base and many times will make the rust disappear. I haven't used it on bolts in place like on a fender for instance . You have to rinse it off with water so it is important that they are quick dried with a rag etc. (air blowing with cause the flash rust to come back . They have to be at least 75% dry before using air to finish drying. You follow up with a rust inhibitor like T9 or similar.
Short cuts don't work.
when possible and after cleaning and coloring (bluing and working) if needed I heat the part to remove any moisture in it as well as opening the pores then cool it in a bath or oil
In sunny California, not a problem. An oven works, sometimes. I've had to redo some parts as "flash rust" appeared.
Not too hot - don't want to change the metal or its properties. Just what I've done for years
You would have to get steel well over 1000F to make a change. I tried 30 weight motor oil heated to about 450F. All I managed to do was stink up the neighborhood.
