Ospho vs. electroplating as Corrosion Prevention

I need some help. I am restoring a car and would like some way to protect hardware and small parts from corrosion. Should I just buy new hardware, etc, or is there a simple way. I have read enough about electroplating and such that I know I shouldn't try it at home, and don't need the hassles of disposing my waste. Someone has told me about Ospho [affil links]. Is it good for what I need ?

I am fixing up an old Volkswagen. I have a few questions. Some parts seem to be galvanized, etc. In what way do I restore these metallic parts, with a corrosive resistant coating ? I just don't want to buy all new parts, if there is anyway to refinish them myself. I'm not looking for chrome or necessarily shiny finish. What are bolts, washers, etc finished with when you buy new ones ?

A company Called "Eastwood" sells an electroplating kit. I don't know if I need to electroplate or just use some sort of conversion coating. What are my "do it yourself" options? I just need some general info on types of coatings and their benefits, etc.

Unless you have had training in hazardous chemical handling, I don't see why you would want to even try something like electroplating at home. Most of the knowledgeable people who visit this site would agree that electroplating should be handled by a job shop and not by hobbyists. My advice is to find a local plater and pay them to do it for you. You will get professional quality and you can let them deal with the chemicals. In addition, they have the experience to tell you what kind of finish you need for your parts. It may be cheaper to try to "do-it-yourself" but I think the environment and your own health are worth a little extra money. Use the yellow pages, your own research, or the list of platers who support this site.
