Default Single Stage or BC/CC?

'68 Firebird RAI 4spd conv.
Starlight Black.
Resto objective: Concours/Factory

Some insist on single stage paint.
Others say basecoat/clearcoat.

I get that S/S is closer to factory finish however, this won't have the protection/durability as BC/CC and will show everything/need regular attention.

My painter has done a lot of black cars that are amazing. He says BC/CC doesn't have to be over the top.

Another suggestion is to go S/S but with clear (PPG Concept, "cocktail").

Scott Tiemann: BC/CC
Level One: S/S
Supercar Workshop: BC/CC

As I understand it, POCI & MCACN don't deduct points for BC/CC provided it's not over done.

Would appreciate the pros & cons.

Thanks!

John,
I haven't tried the cocktail, but it is a viable method. Kind of the best of both worlds if you're going to have UV exposure on a concourse/driver oxymoron.
You've seen the pictures I sent you of the silver '68, and that is BC/CC with three coats of 2002 Clear. I doubt if that car sees 5 days of sun exposure a year.
I admit that if I was in your shoes I would use the DCC Concept single stage.
Steve

ID:	533657I love S/S paint when done right. My car was painted in 1988 with MartinSenour Acrylic Enamel. Granted, it is kept garaged , but I drive it about 1800 to 2100 miles a year. Although it has tiny chips and fine scratches , It still looks awesome.
If I ever decide to repaint t, It will be done the same way.

The single stage is the same chemical makeup as the clear only without pigment. So the uv is still there. This is why you can as your term (cocktail) can be done. This I have done with the thinking it would enhance gloss. this is unproven afaik

B/C is a must on a metallic color especially if sand and buffing is in the plan. but not so much on a solid color. The solid color can be sanded and buffed w/o the clear.

The clear over solid color adds nothing to gloss or life to job. Single stage also is less costly and less time to do. Repair is also EZer to repair . One more advantage could be that if at any point in paint process you need to do a repair or improvement to job you can just spray another coat. some shops paint car then sand it out and apply more coats as a final finish.

Factory clear coats every vehicle now due to there paint system

But in ether case a good shop can produce the same result. A excellent job.

Whatever you choose make sure the shop you choose is comfortable with the system you choose. This can affect the job more than you may think

one other point to consider. most shops now are geared to do BC/CC due to the fact that there mixing system is a B/C system . that means there tint bank is all base coat tints. The clear is common to any color they mix.

In the body shop world now hardly anyone uses S/S unless they do fleet work

I've read that black cars will look 'more black' with a single stage paint, but don't know if that is really true.

I used PPG DCC 9300 single stage on my 67 GTO. Sprayed it about 10 years ago and it still looks great.

Almost all the cars I've had even new I've kept with BC/CC the clear delaminates after a while. the '04 GTO I bought in '05 added the '05 style hood and was painted in Sikkens BC/CC and it delaminated almost the same rate as the original paint. Now my wife's dark green '02 Avalanche still is decent except just now some on the hood. Single stage is sure easier to touch up.

I disagree clear over color in single stage does not add depth, my 78 was done that way with Glasurit polyurethane and it definitely added depth to the shine. Done in '88 and still looks good-except from burnout chips

Don't know if it's still offered but the old Ditzler acrylic enamel covered with clear urethane with hardener is a killer finish.

It’s Black......id Go the single stage route.....just put 4 good coats on....let it set in the blistering sun for a week to gas out. Then start cutting (sanding) ....and then buffing. Iam not going to give out my secrets to a near lacquer looking finish and the compounds I use.....but good luck..what ever you choose.

I would say 99% of the shops out there ....would refuse to paint a guys car if he came in with a paint system different than theirs....I know I would.
