thought i'd show some interesting pics of one of the current builds taking place.

i had the complete truck chem stripped including frame. i had found in the past couple i'd done like that since there is no oxidation inside the frame any longer because of the dip, i was getting some slight rust wash out as it was reoxiding. i'd notice it after say washing it or running in the rain. i really didn't want to try painting the inside of it. i had seen where another member here had had his glavanized. i was interested in that so i looked into it and found a source locally.

i prepped the frame doing the typical deburr and metal repair, updates... and dropped it off. this is a serious industrial place now. i saw they won an award recently for their work on the new parking structure here at the charlotte airport. i show up with this puney bronco frame and kind of get the "that's all" look. well i get a call 3 days later that it's ready to pick up. sweet. i love service like that!

bring it home 4 days after drop off. looks pretty darn good. being hot dip, they must of had some runs in it, so they ground them down an sprayed a galv/zinc based paint over those areas. if they hadn't done that i might have considered leaving it that natural color for a change of pace and looked pretty unique. you know i'm all about unique.
inside is really well coated. i see a few minor spots that didn't get covered, as there must have been some acid still in from their cleaning process before it goes into the hot dip bath. i think next time i'll tell them to tilt the frame to allow it to drain better. as a whole a 99% improvement this round.
i decided to paint it. i shot it with a ppg DP90 and then with a gloss black top coat.

this will be a great way to help keep these old dogs around for the next 30+ years.

cost was 250 for the galv dip, well worth it when you' re this far into a build imop.

Nick,
That's nice!
Did the galvanizing process cover up the VIN on the framerail or could you still see the stamping?

That's looks good. I found out about a local place that will do hot dip about 2 years after I finished putting my body back on. :(

if you know where the serial number is you can find itbbut can't really read it. i spose i could sand it back down before i paint. with the hot dip there isn't a mask you can do since it's going into a 840* bath then gets quenched.

Can they chem strip the frame onsite prior to be galvanized or do you have to do that elsewhere?

i'm having it stripped at a dif vendor, then i bring it here and it get's dipped again. now i need to find out if the galv vendors dip will get all the junk off like the stripping process does. if so that will save me & my customers an additional expense.

When I spoke to a local guy that had his frame dipped the said the acid bath will take off rust but doesn't take off all types of paint.

that is what i was thinking. the first chem strip process gets it spotless, i think this second dip is just a quicky clean up en route down the glav line.
this particular frame had all kinds of nasty thick undercoat shot on it here and there, overspray & lots of grease. it was pretty nasty.

no prep required since it was fresh out of the tank. there where no greasy finger prints on it... if it had been handled a bunch i would have wiped it down with a cleaner. i saw no point in sanding as there was a nice surface on it to grab hold of. i shot 2 coats of the dp on it and let it set up well before top coating. it should be quite tough now.

body is getting painted this week so i will begin to get the chassis back together and have it ready to drop the tub on after it's painted and spray lined.

The dip that the galvanizer does will remove some rust and light scale. It is not designed to remove paint and grime...that needs to be done ahead of time. Sand or bead blasting the frame also works well.

I believe I could still read my VIN number when I had it done. $250 is a good deal. In reality, thats probably their minimum and if you had two or three it wouldnt cost 2-3X more... I got the HS buddy rate of $125...with a few other perks...it basically just covered their costs. I hope that your DP40 sticks better than the Sherman William's Industrial 2 part I used on mine...and that was with a fresh "sweep blast" . The rattle can sticks well enough to the few chip spots. Hopefully, your epoxy will stick better than my polyurethane. It is very tempting to keep it in plain zinc, but it will eventually look chaffed and chalky if you dont top coat it.

Here are a couple of mine from a couple of years back. Sorry to post so many, but I know how you guys like the Bronco-porn...and I think some of them are PHAT.
