Hell, I think it looks pretty cool. Def something different. How much did it cost you to do or have done?

13 pieces for $10 a piece 
im going to bring a **** load of nuts and bolts he said like 2 bucks for big bolts and like 10mm bolts .50 cents I think it would look nice

actually not sure I should look into it! He said it would but you never know! <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by 4F CHR!S »</TD></TR><TR><TD CLASS="quote">looks pretty good, does zinc plating prevent rust?</TD></TR></TABLE>

Well this was rather discouraging to read...
<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote »</TD></TR><TR><TD CLASS="quote">Poor Performance from Plated Coatings
Zinc plated coatings are not suitable for exterior exposure applications. Zinc plated bolts and hardware fittings such as gate hinges will not provide adequate protection from corrosion, and will rarely last more than 12 months in exterior exposures in most urban coastal environments.
Zinc plating has been used in industrial coating applications from time to time, with very poor results. Industrial Galvanizers joint venture galvanizing operations in Bakasi, Indonesia, PT Bukit Terang Paksi Galvanizing (BTG), was commissioned in March 1998 to reprocess a large tonnage (approx. 400 tonnes) of cable trays that had been electroplated. The zinc electroplated coating had failed prior to delivery to the project resulting in the rejection of the entire consignment.
The client requested an extra-heavy hot-dip galvanised coating to replace the zinc plating, and BTG was able to apply a 100 micron coating to the 3 mm thick cable tray sections - this is around 50% above the required minimum standard for hot dip galvanised coatings applied to steel of this thickness of and over 10 times the thickness of the zinc plating.
Zinc plated products have an attractive appearance when new as the zinc coating is bright and smooth, where a hot dip galvanised coating has a duller and less smooth surface. There is typically about 10 times as much zinc applied to small parts in the hot dip galvanizing process as with zinc plating. A bright, shiny smooth zinc finish on builders hardware (bolts, nuts, hinges, gate latches, post shoes) indicates a plated coating that will not provide adequate corrosion resistance and will rarely provide more than 12 months protection in most of the coastal population centres.</TD></TR></TABLE>

If by poor performance they mean the zinc is doing what it's supposed to.... the article blows it out of whack a little.
Cathodic protection using zinc is a good corrosion protection method. However, zinc plating as the article mentions, is not a good method because of the layer thickness. Hot dip zinc galvanizing is a better method.
If you are getting the fasteners coated for cosmetic purposes, then go ahead and get it plated. It will be cheap and probably last as long as (or longer than) you want to keep the car unless you live in a particularly aggressive environment. If for some reason your original rusty steel fasteners aren't enough for you, then look maybe you should look into SS fasteners or properly zinc-coated fasteners.

Re: (xunsungheroesx)
I just asked and he said it is hot dip. They say they coat all kinds of brake rotors and what not to fight corosion. But only time will tell! Also he just called me back and said he would guarantee it and if it starts looking like **** he would re do them. <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by xunsungheroesx »</TD></TR><TR><TD CLASS="quote">If by poor performance they mean the zinc is doing what it's supposed to.... the article blows it out of whack a little.

Re: zinc plating??? what do you guys think of this?? (redEH2)
Zinc coating can be done in three methods.
Electric galvanizing, hot galvanizing and then the galvanizing that is done further so you get that yellow surface.
They resist rust, Electric galvanizing is used mostly on bolts and stuff, provides decent protection. I think cars are galvanized like this. The galvanizing is attached to the chassis with electric current, when the car is dipped into the moat.
Hot galvanizing is done with hot liquid dipping
The yellow surface is done somehow, dont know exactly.
Zinc coating is better than nothing, that cant be argued against. It would resist rusting if the coating is ok and not damaged.

Re: zinc plating??? what do you guys think of this?? (Flashmn)
did you know on the golden gate bridge, they have storage compartments that are made specificially to hold blocks of zinc?
the zinc block is there to prevent rust. what happens is that the steel rust because it lose their electron, but the zinc is there to give their's away. so from metal to metal contact the electrons transfers to where ever it is needed.
pretty cool, i think that how it works.
p.s. in loving memory of zinc block, bravely standing in rust's way, that others may live.
