1979 Datsun 280zx - Safety Orange!

Post by Lil Neon on January 4th 2011, 5:36 pm

Hi all! So for my second project on here I'm going to be rolling on the 280zx. It was a faded gold/brown and was starting to develop some rust spots which these cars are notorious for. Hopefully the Rustoleum will help kick that problem in the *** Smile I'm using a mixture of 2 parts paint, 1 part Penetrol, and 1/2 part Mineral Spirits <- the same mixture bigmike used on his great looking 240sx. I stripped as much paint as I could with a DA sander + 100 grit sand paper. Then I went through with the block + 400 grit.

So I hit the rusty areas with the angle grinder's rust/paint remover and took it down to clean metal. Pic of the car prior to any work:



What it looks like after the first coat:





Even though I went back through with the 400 grit + sanding block there are still some marks from the DA sander visible through this first coat. I didn't notice these on the first car I did so I'm wondering if anyone knows if they'll disappear with more coats + wet sanding??

Tried to get a good pic of the DA swirl:



Any insight would be excellent - thanks! Oh and the car looks alot more orange than it really is. Still lots of brown in it.

Those DA marks will disappear after a LOT of work and several coats. This is one of those times where a good primer coat would save you much effort over just rolling paint. Prep work is 90% of a paint job. I got out of the bodywork business back in the late 80s and though the materials and pricing have all changed, prep work has not.

Not trying to be a wet blanket, but you'd be so much farther ahead if you sand it back down where the DA marks are and add some primer before rolling more paint.

Hmmm yeah I was afraid that may be the case. That also explains why I didn't notice any marks on the first car I did - because I put down a primer coat on that car. Grrreeat. Thanks for the response though, Noah!

Are you going to strip the car again? If so will you re sand the bare metal with 380 grit paper?

More coats will not get rid of the DA sander marks, If its only in a few small areas, wet sand those down with 400 using a block of coarse, and then primer and wet sand with 400 again, mist coat your primer with flat black it will help you see any imperfections.

If its on most of the car, I would dry sand with 220 then cover with 2k primer and then wet sand that with 400

Thanks for the replies everyone! I dry sanded the whole thing and am currently in the process of priming it. So what's the deal with the spray primer? It just settles differently on the surface, and thus masks those nasty swirls??

Primer is thicker than paint. It is designed to fill those swirls. If you simply prime over that fresh paint, the paint will "outgas" and lift the primer and subsequent paint coats off the surface.

What I would have tried, would have been to apply unthinned paint to the affected areas.
Then if that didn't work, I would just smear bondo into the scratches. Let it dry, sand it smooth.

You want a filler primer to fill sanding scratches in metal.

That will look good in orange, and I like the Period-correct turbine mag wheels, but with the two of them together, someone might think you're going for a "Dukes of Hazzard" theme with the car.

Haha thanks! I was thinking of naming it "General Z" Razz

Alright now with the rolling. I don't remember having such epic roller marks. I'm talking huge voids between paint. On this coat I've tried to just apply some more pressure to push the paint out for a smoother roll and I've also tried adding more paint to the roller when I roll - but that just seems like I'm going on too thick.

Okay got coat #2 on today. Didn't have too many issues with the rolling - maybe the rollers just needed to break in a bit or maybe I just needed to get the hang of it Razz





That primer coat eliminated my sanding marks too. This pic was taken pretty soon after painting so there are still some bubbles and other crap that needs to be wet-sanded out:

Welllll I had planned on putting on another coat today after work - but it appears to be too cold. I tried to roll a lil bit on the hood and it would not level out. So I guess ~18 degrees is too cold dork

The desert southwest does get cold in the winter. Here in Tucson last week we had a 23 and a 26 degree morning. Granted, that was below normal but not a record. I now know why you see heavy long coats in some of the old time cowboy pictures from down here. grin

Well I did get all of the rolling done finally but I've been putting off the final wetsanding, buffing and polishing for the paint to cure and for it to stop snowing Razz

I'll try to get some pics up this week even if they are pre-final wetsanding Very Happy
