undercarriage semi gloss black
 

Guys, lookin for some help in painting the undercarriage and firewall on my other 68 nova ss in the black semi gloss look, some like it a bit flatter ,but a prefer a little shiny look... lookin for a mixing formula to achieve this look..currently the underneath is in a PPG DP 90.. it is ready to spray and would like to make sure I get it close...any help appreciated...PM me if would prefer to sent a mixing formula ,would prefer a PPG mix as this is a PPG store here in florida locally... thanks,Chris Teed

Hi Chris,

Just ask your local PPG store to give you there M148 flatting agent chart. I have it at the shop not on a computer. I used Omni Black base with some hardener and the flattening agent on my sub frame and under side of L79. I used the egg shell mixing ratio. I sprayed out the semi gloss and it was to glossy for me. I used Omni M148 flattener and MTK base.

Re: undercarriage semi gloss black
 

I agree with Jason's approach with the only difference being that I used PPG's Deltron line - just personal preference.

I sprayed:
- DMC902 - Concept Carbon Black
- DCX61 - hardner
- SU4985 - matting agent

Like Jason said, spray it out first to make sure you like the gloss level - I didn't and also like Jason would have preferred a little less gloss with our finished product, but I'm hoping the gloss will tone down over time...

I've been using SEM Rust Shield in 'black' thin no more than 10% ...dries down nice. Tad flatter than the Concept. I used to use PPG with 'flatner' in years gone by but found the 'flatting' agent to be wildly inconsistent from job to job.

The DP 90 you already have on there is probably the &quot;by the book&quot; mix of the DP and hardener, so it's probably a little dull. I had an experienced painter advise me to add some reducer to give it some gloss (just a little). DP hardens like a rock and seals the surface so I decided to leave it that way, without a top coat of paint. I practiced a lot on some scrap metal and wound up with (what I think) is the perfect finish. I shot it wet with a lower pressure than recommended. Like others have said, you just have to play with the reducer and your gun settings and spray test patches until you're happy.

Omni is the inexpensive way out. I had to put down 4 coats of paint for it to cover. Marlin most likely used 2 concept is a lot more expensive.

I have also used sem rust shield on various projects.

Re: undercarriage semi gloss black
 

Ironically, I sprayed my Yenko Deuce with DP90 mixed as a sealer (achieved by adding reducer to the concoction), and while I liked it for my Yenko because it matched the original black sheen it would have been a little too flat for Benjamin's '69 Nova. So, that is why I went with the topcoat / flattener method. I did learn that if you keep a nice coat of spray wax on the DP90 sealer coat, it will keep a real nice sheen - just keep it from being exposed to direct sunlight for too long.

Everything black in this pic is DP90 mixed as a sealer, I varied the reducer ratio to change the sheen on the various components.

Re: undercarriage semi gloss black
 

If it's a 68 any chance the bottom was ruby red?

My 2 cents. Frt stubs vary on amount of paint applied. My original deuce had almost nothing. I tend to think the material was one of 4 brands of laquer. Unbuffed black laquer has a dull blue sheen. Opinion: Most anything you put on will be much better than the original stuff. Original old dp before it became dplf laid flatter and looked closer. Actually, if you let the dplf age in the sun, it starts to look like the original faded out laquer :-)

Re: undercarriage semi gloss black
 

Also, DP90LF vs DP90 is not black (enough) do a spray out and look at it in the direct sunlight and compare it to another black. JMO. It does lay down nicely slightly reduced. JMO

Yes SPI epoxy is a very good product. I have been using it for a couple years now . A lot of guys use this for a chassis paint or underhood black with excellent results. Check out their website as they have a good user forum on there if you have any questions.

http://i125.photobucket.com/albums/p...ailpics012.jpg I still use that gm reconditioning paint a lot. Its supposedly a remake of the original but it goes right in the gun and that's it, dries quick and has a decent look. Not flat and not semi gloss either.pardon the dust in this phot but you can get the feel for it.

Same here. Heard good things, but haven't used it.

Re: undercarriage semi gloss black
 

Schoneye, are you shooting Sikkens or some other brand??

Re: undercarriage semi gloss black
 

Sikkens. I like the way the base lays. And it's what the shop uses where Joe works.

Re: undercarriage semi gloss black
 

We have been using SPI primer for years.The best out there.Fine to use as a top coat on the bottom of a car,but never if it gets sun light.Sikkens rally black is very good.

Where do you purchase this Gm paint from???
I work at a GM Dealer and the part number shows invalid???
Thanks

Re: undercarriage semi gloss black
 

While I have not used it, John Deere blitz black looks a lot like the old GM product.

Re: undercarriage semi gloss black
 

I ended up using SEM Trim black on my floor pan and sub-frame. I used it over PPG epoxy primer in gray. I couldn't be happier with the results. Here's how it came out.

Re: undercarriage semi gloss black
 

I still use Eastwood Chassis black. Not flashy but it works. And is close to the real color my frame was when new.

Re: undercarriage semi gloss black
 

Very cool; thanks for sharing.

Re: undercarriage semi gloss black
 

Thanks for all the help and advice.. I ended going with a PPG DCC 9300 black,which is an acrylic urethane. with a 4985 flattening agent,dcx 61 hardener and a DT reducer... I like the semi gloss look...was slightly more than a semi gloss, but I would add a few ounces of flattener on the final coat to tone it down a little.always remember what each product role is on the formula...it you add more hardener it will get more shiner..i also used a DT 885 reducer that is used for some hot temperature . it dryer slower and will give you more time to spray the underneath of car. with it drying evenly..will post some pix hopefully tomorrow.
