: Painting media blasted parts?
Albbies1 Jun 25th, 02, 10:33 AM Friends
I have a couple sets of 66 inner fenders and radiator supports that were recently stripped via sand blasting. I have a couple questions to anyone that can help.
1) Anyone use the Eastwood's paint, Under Hood Black and have any comments on its quality etc.?
2) Does the inner fenders, radiator support parts etc. require a primer before spraying the mentioned paint above? I know that question sounds dumb but the factory pieces mentioned did not look as though they were primed and the finish coat appeared very thin.
Thanks all,
Dwaine

ELLI Jun 25th, 02, 10:51 AM I don't know how agressive of a media your blaster usedon your stuff, but mine made the surface of the fenders really rough, so I primed a few coats to even it out then sprayed black Dupont Lucite on the pieces. I would say prime them no matter what. As for Eastwoods stuff, I have no used chassis black, but have used other products by them with excellent results.

Randy Mosier Jun 25th, 02, 12:08 PM Eastwood products are pretty good for the most part. They sell a product called Corroless that you actually as a base for the Chassis Black. See if this link works, and read the description of the product.
Okay, the link doesn't work. Here's the homepage for Eastwood.
www.eastwoodcompany.com (http://www.eastwoodcompany.com)
From the index on the left side of the page, click on 'specialty coatings'. On the following page, under the heading 'Specialty Paints and Coatings', click on Chassis. Then scroll down and check out the description of the full resto kit, about the fourth item down the page. Click on the picture to get the description. They recommend the Corroless as a base coat for the chassis coatings.

Thanks guys for the quick replies and assistance. Mat, I don't know what the pressure was when the parts were cleaned. I dropped them off locally at Eagle Auto Stripping Co. here in KC/KS. They do everything from complete cars, frames, doors, fenders etc. Have done nice work for me in the past and present.
I have seen page displaying the Chasis Black products. I thought Chasis Black was made for the cars underside and frame stuff etc. I am looking at the sheet metal parts, brackets etc. under the hood. I guess this product "Under the Hood" is used to provide a semi gloss "correct" finish. If you all don't mind I have one other question for you both or anyone. Thanks guys and I will also check out the link.
1) Do I have to block sand prepping the metal prior to painting? What grit should I use if that is correct? I might have heard here in the past that prepping the metal with sand paper was required before applying the paint on blasted materials.
Thanks again

Donnie1 Jun 25th, 02, 3:01 PM spray them with PPG's DP90 epoxy primer sealer.
this will give you the black color your looking for, put two coats on and your done.
the por15 and Corroless are for cars with rust no need for it if your parts are rust free.

Randy Mosier Jun 25th, 02, 4:27 PM They do sell Chassis Black in high gloss also, if that's what you're looking for.

Thanks for your info guys. Randy I am going to go with a semi gloss flat black color which should be "correct" for the chevelle parts I am trying to repaint.
Don, I appreciate the insight and info on the mentioned PPG black primer. I will stop by the loal auto paint store and check into it further. I might put a coat on followed by the Eastwood Under hood Paint. I would hate to leave a primer unsealed even if it is an Epoxy. Thanks folks for the assistance in my questions.

Freddy Mercado Jun 25th, 02, 7:45 PM For the parts you mentioned, Eastwood's under hood black is the correct color. I media blast and paint my own parts. After blasting, I clean all parts with a product like Prep-Sol and apply two coats of self etching primer. I then apply one coat of regular primer and paint the part. I have not had any problems. Your paint job will only be as good as your preparation. I would also like to add that I am NO expert, by any stretch of the imagination. This is only my opinion. Here you will get expert opinions.

sevt_chevelle Jun 25th, 02, 9:41 PM Dwaine expoy primer like dp90 on bare metal is not recemmend by PPG or the car manufactors. I would coat the bare metal first with a self etch primer like PPG's dx1791, dupont's variprime or sherwin williams 980. Self etch needs to be sealed before you topcoat it. Depending on how rough of sand they used to blast your parts, a 2K primer can be used to topcoat the etch. K36 from PPG can be sprayed as a wet on wet sealer and plus it has a good film build to cover up those pits made by the sand.
If your parts were sand blasted then no you dont have to prep them by sanding them first the sand blasting did the same thing. You only have to sand parts that have been media blasted from plastic. Plastic just doesnt etch or bite into the metal like sand does so you need to sand it.

you do not need to use a self etch primer before you use DP90 and you do not need to top coat it unless you want to. this is a two part epoxy primer sealer.
after the activator sets up its not going anywhere, and it is real close to the black that G.M. used.
ive been using this on sandblasted parts sense 1992 with no problems.
look at my pics theirs two shots of my frame with this on it.

sevt_chevelle Jun 26th, 02, 5:59 PM Dwaine I highly suggest you dont use expoy primer on bare metal it is so outdated and under performing product in my book. The only way to coat bare metal is with a self etch primer NOT EXPOY. Expoy doesnt fight the rust like a etch will. Once that expoy gets scracthed it starts to rust and spread, but the etch willnt.
Take a panel painted only with expoy and then one with etch and put a scracth down both panels, then put outside and wait for the rain. I promise you the panel with the expoy will have rust forming and rust growing under the expoy as well, were the etch will have none. Dont believe me try it and find out for yourself that expoy just SUCKS...Eric
