used an old school trick on the radiator rubber pieces, I stuck them in boiling water, than spent some time with a nylon brush at the sink

I was even able to get one part number off of them for us 3966800, still trying to read the other one, I recon there are two types maybe tops and bottoms

conincidentaly there is someone selling four of these on eBay right now for $67 bucks, [pronounced] Highway Robbery, LOL

of course the ones that told me their part number seem in better shape, ha ha

Yeah, that stuff works great! Just be sure to degrease and de-dirt the parts first. I usually hit them with a wire brush too.

Tops are shorter than the bottoms. To make matters worse depending on the radiator you have there are two different kinds as well.

As with your rivnuts you found the larger and thicker radiators used different rubbers.

so after literrally days of wire wheeling and soaking in phosphoric acid I finally got the top radiator support / core support down to bare metal, but even after that underneath I found some more rust so back in the acid bath it went

and after navigating around that white sticker I finally said forget it and wire wheeled it off

I share this story because this is a massive undertaking every square inch of this front core support is covered in rust, so much more work than I expected

man I just had to see some results, something getting done, so I powered through and got the rest of the chrome bits painted black, also through in that UFO (aka the new bottom air cleaner) in there for good measure

so lets do a roll call on Chrome pieces (since I am amazed how many parts make up that front core support)

2 x headlight bezles (already painted)

2 x headlight rings

2 x grille moldings (upper and lower)

hope I didn't forget anything, as I am almost out of that Adhesion Promoter

Alright I was able to read the part number off of the other Radiator Retainer Pad as it is called by GM

Part Number 3966804

Also that first part number 3966800 has been supposedly superseded by part number 371189 carried by Summit for $9 bucks each

not to be confused with part number 6264100 meant for da Big Block Chebby

just trying to help folks, just trying to help

so every mornink before work, take out the pieces from the acid bath and hose the loose rust off of them, maybe scrub them with a steel brush by hand in the trouble areas, than flip em upside down and soak the other side of the tall pieces, rinse, lather, repeat

tired of wire wheelin I decided to put on my big boy pants and get one of these media blaster buckets from Harbor Freight

this is the biggest one they got holds 110 pounds of media with the 20% off coupon it was just north of $100 bucks

so naturally to try it out we (my Mopar buddy The Seth and I, aka the Royal We) got sum Walnut media, ie the cheapest stuff like $25 bones fer 25 lbs

FIRST MISTAKE

Trying to blast walnut shell through that gizmo is like trying to play tennis with a Basketball

when they say FINE on the box, thats relative, as there is probably, Ultra Fine, or Super Fine, or maybe even Ultra Super Fine, ha ha, anywho it was 24 grit, way too big

it did not work even after buying bigger ceramic nozzles

so we hopped in the Six' Four and headed back to da Media Store

this time dropped $30 on 25 lbs of glass bead 80 grit, pronounced "legit"

and then we were cooking with Propane!

pics a bit dark as we were in The Barn, I was borrowing The Seth air compressor as I am currently in between comressors, ie I aint got one

couple observations:

a water trap device in the air compressor line is a MUST, moist air is the enemy of the master blaster

media blasting leaves a different surface on the metal than a wire wheel, you would think a wire wheel is abrasive but media (and I know it depends on what type, but speaking strictly of glass bead) leaves a rough metal surface, a wire wheel does not, or not as much at all

decided to blast the core support as it has many twists and turns and zigs and zagz in it making it hard to navigate a wire wheel through it all

decided these parts are as clean as they are going to get, and I had to start shooting primer today or I would go crazy

even a blind squirrel finds a nut sometimes, check out this deal on my favorite Rusty Metal Primer at AutoZone, normally $6.50 a can, today buy two and get em for $5 bucks each, I love how well this spray covers

so I decided to stock up

so first up was the upper grill panel I want to show you the phases I went through in order to get it ready for primer / paint

now I aint saying I'm and expert an this is how you do it, I just want to share what happened with you

Pic 1 - original part simply removed off the truck

Pic 2 - soaked in acid overnight (some lose paint, some rust came off)

Pic 3 - giving the acid a hand by wire wheeling the rust and paint off (though the part looks shinny there is still rust in the impossible to reach areas and in the pitted metal) so back to the acid bath it went

Pic 4 - this is the interesting part, I think some call this phenomenon pickeling, the left side of the panel was soaked in acid overnight and after washing off the acid with water it turns that yellowish haze and starts to surface rust (the right side was not dipped in acid)

Pic 5 - after the entire piece was soaked in acid and washed off with a garden hose and left to air dry, this is about 2 hours later, looks like a step backwards, but this is all just surface rust and comes off easily with a wire wheel

... continued in next post ...

Gregski 04-07-2016 11:22 PM

Re: Restoring Rusty

continuing on...

Pic 6 - after wire wheeling the surface rust off

Pic 7 - primered (sorry I didn't take a better pic yet when it dried cause it got dark)

so again, there may be a better way to do it, but this is how I did it, and yest it was a massive amount of work, but you just have to press on

followed the same process for the lower panel, this time I will show you the backside of it, as it was all covered in rust, so here is the original piece, then pickled half, then all cleaned up

its just a lot of work that's all it is

the headlight buckets were already black, but rusty, so I stripped them down to bare metal, than primered them than shot them with Semi Flat black then clear coated them with Matt Clear - they should give the entire gitty up nice depth, ha ha

well so at this point I wanted to say we've blacked out or painted everything that was going to be black on this core support, and then I realized I forgot to paint the hood latch mechanism, which I want to be black to add some contrast to all that soon to be greenery

dope, I just realized it's hidden under the upper core support panel anyways, dang

yes these next few posts are dreadfully boring, but if I had to suffer through cleaning and painting these, you will have to suffer through scrolling past them, lol

I call these the inside grille brackets

swung by Jerry's paint shop and got 5 cans of paint matched to my factory code for the core support

check out their wonderful fasteners selection, I love this type of display, it's the actual fasteners you will be getting, not some black and white photo or outline in a book, (I'm looking at you NAPA)

too bad they still didn't have the silly white plastic slip in nylon nuts for the grille
