Single or Dual Paint coats on a vintage Porsche (1969) ?

[csimeon]

I am finally almost done with most preparation work and almost ready to paint.
The paint shop proposes a dual stage paint, modern Base Coat & Clear Coat.

I was preparing for a Single paint before I went to the store, for originality and I think the overshine is a thing of the latest years. Am I right in this point? Are there other factors to influence choice and what's your end conclusion

Should I yield to the professional advice?

I should say for those about to contribute their thoughts:
1- I will painting parts , not the whole car, the parts chosen were those with defects
2- The color will be the original color Porsche Irish Green
3- Color matching was checked against the Porsche prescription and was found to be correct, but the exact match will be made with a spectrophotometer .
4- The car has been repainted at least 3 times (the last coat was the original green again)
5- The paint finish was mixed between parts, as I bought it : some were single others dual... yes all were green, haha.
6- The car is to be a good looking vintage road car, not a show piece
7- The car will be garaged at all times it's not used

This is how the car was after the initial wash as I bought it, not bad. Up close their were discolorations from bad buffing and local touch-ups. There were also areas where too thick or badly applied or cured filler was forming cracks - no rust.

Well, I'm not a paint expert, but seems to me that if you're not painting the whole car, the painter should use whatever most closely matches what's there. Single stage can be polished out to a high shine, but it will never match a color/clear coat finish and vice versa. So the question to me is, what's on the car now that you're trying to match?

When I start my resto to a 71 Irish green coupe I think I'll go with bc/cc but I'll be repainting the entire car. You should also post his on the paint body forum. Lots os folks in the know there. Before you do, post more pics of your car. Man I love that color( for obvious reasons!

Use single stage. The value of the car is in its originality, not the shine of the paint.

My 1966 is Irish Green 6606 and it's getting single stage.

First - Irish Green on a long hood makes me very hard.

Second - Single stage!

[rattlsnak]

go with single..

[UrQuattro]

Absolutely agree. Single stage.

[merbesfield]

what is single stage? is it the same a lacquer? i know my car originally came from the factory with lacquer. i know what bc/cc is. thanks

i agree with the above as far as single stage.

theree are different types of single stage paints out there. acrylic and urethanes to name two. but the looks of a nice single stage on a classic car "is well classic"
go to the paint shop and see what brands your code paint comes in. i painted my race car this last year color 337 i think? it is a lime colored green and i could only get it in a ppg or glasurite in the color, i was looking for dupont because i had left over supplies. but none the less a good single will look the part.

Great question. Most paint shops will want to paint two pack or even water borne (heaven forbid) because that's the system they have installed in their facility. To switch for a painter is difficult because they have to re-learn their craft to a certain extent, with pressures, formulations and application techniques.

You CAN make two pack look gloriously authentic: I learnt this process a while ago, and it involves treating the catalysed paint as if it were single stage, sanding and flattening between coats. Totally time consuming but vintage results. There is a great shop here in NZ that has done exactly the same with an alloy F. GTO replica which looks like it was painted 25 years ago.
Bottom line, yes you can get it, but the labour flatting it will cost. 2 Pack is nasty to spray, but lasts.

Difficult Q, if pushed, I'd be spraying single just for *****s & giggles cos it is so nice. Illegal in Cali??
