what color primer

Hey folks,

Maybe I'm overthinking this a little but...I'm planning on painting my 48 chevy p/u a metallic copper color. I was wondering how much the primer color is going to affect the final color. I have Nason "buff" colored primer right now. What change would light gray primer have on the final color. Like I said I already have the buff colored stuff and thought that the lighter color would maybe help the paint to "pop' a little more. Your thoughts please. Thank you.

Barry

"Overthinking" huh? no, we never do that! You know in less you have a lot of time on your hands......and spare money I would just leave it alone. The buff color primer should work well or you could have used the old red oxide looking color.

If you were using really crappy paint (and some guys will say that Nason is just that) that doesn't have a lot of pigment then you may have a problem depending on the color combination. Ask your paint shop if they think it will work ok or should you upgrade to Dupont Chroma or the like....good luck.

Another thing to consider, as if you needed another thing to think about . The color of your underlying primer will play a factor when you receive a rock chip. A light colored primer on a dark colored car shows up more than a similarly colored primer when and if you get rock chips.

Using red paint as an example.......would a light colored primer tend to make the final color brighter (lighter) than a dark primer ?

Just wondering.

Thanks !

When painting a metallic over-coat such as silver or copper it would be best to use a contrasting substrate under the top coat. I would recommend dark grey primer.

That is dependent on how well your paint covers. A cheap line may be affected whereas a quality paint will not.

Not entirely accurate. Using a cheaper line really doesnít effect how many coats or how well it covers. Using a cheap line of paint will however often have problems with color matching and present problems with blending.

This is not true at all. Low end (and some of the "better") paint lines cover very badly and can take more than 8 coats to cover. Also reds and yellows are notorious for having poor coverage.

you can always tint your primer,and you should use a tintable sealer.As mentioned before some colors are more transparent than others and may take more coats to cover,you'll have to really look close as you paint your base and alternate your direction on each coat...(for instance if you go front to back on your hood,the second coat should go side to side then the third diagonaly) and dont be surprized if it takes six or more coats to cover uniformly.The color you've chose is a difficult one to spray for a pro and many pros screw them up,so be prepared for an up hill battle,the differances in primer colors "pop" is more a problem for candies or Tri-coats.Your color is opaque not transparent so use a tintable sealer only because light spots wont be so noticeable,(if there are any)you'll need lotsa light and even more patience.but it can be done.I get the impression youve painted before so your already ahead of the curve. Good luck to ya.

occationaly I'll paint a transparent color like indigo blue with Nason because of the cost factor, chromabase can exceed 400.00 a gal way more, so I'll use nason...Personaly I dont tint sealer...I dont even use sealer anymore...But what I do use is my old nason basecoats mixed up to an aproxement close color as I'm going to end up with...Thats my sealer,three coats of that to fill sand scratches and end up with a uniform base for the new color.I've found some chromabase colors hard to cover as well,but no differnce between the final outcome.but for someone new to painting I cant recomend 800.00 a gal paint... to many things can and will go wrong...nason works very well if done correctly

Donít tell me that high-end quality paint will cover better than a low quality or cheaper brand. I have a 57 Ford wagon a customer wants me to redo because it was painted previously with Dupont Chromasystem and didnít cover properly. $700.00 dollars in paint and you can see the primer through it.

You guyís boast high quality products like youíve got stock in these corporations. The only ones making money with these products are the corporations that manufacture them and the jobbers who push them. As far as Iím concerned, for their costs they donít perform to my expectations.

If they did, I wouldnít have to redo this customerís car. On the other hand, if they did I wouldnít have to redo this customerís car.

And you can quote me in your next post.
