Advances in paint repair and correction?

[aschen]

I made it most of my life without hearing the term paint correction, PPF, ceramic coating etc. It seems like there has been a lot of advancement in the last decade.


My 930 has 80% great paint. It sat outside for a decade when it was a 25k used car. The roof paint is oxidized and thin. The passenger rear flair is heavy orange peel (I think from bad repair or hot oil tank). Otherwise the paint is nice and age appropriate.

I have historically thought, respray the car or nothing. Has this changed in modern times?. Is there a good primer (a pun?) on current tech?

Would a good shop be able to spray just the fender & roof and blend? It is 41 year old Winerot metalic.

TIA

Was Porsche paint single stage back then?

[aschen]

Google AI says single stage. I am not sure of the implications though. Its metallic and glossy in the bulk of the body area. I would have thought there was some clear coat but I am completely ignorant on this stuff.

I'm not an expert on Porsche paints by year but I think '84 was still SS. IDK what the painting restrictions are AFA buying in TX but there's always MX for anything you need. I find SS to be really easy to spray but I grew up with NC lacquer, then acrylic lacquer and finally acrylic enamel which we refer to as SS.

If you want to become a YT trained painter visit Paint Society. Here's the results for SS:

Metallic paints have a clear coat.

Last time I checked, a gallon of decent automotive paint cost just over a brazilion dollars.
Good thing labor costs have gone down to keep things in perspective


A decent driver-quality paint job can easily cost $8k or more, $15k for higher quality (cars and coffee) paint with a show quality paint job hitting between $35k and $100k.
Heck even a top of the line earl scheib paint job can be over 2 grand, insects and all! (masking extra of course).

Just dumb.
They're going to price themselves out of business and together with stupid enviro-regulations, will be a boon for rustoleum!

Thanks guys. I have a lot to learn.

I have owned this car 30+ years and would consider springing for a decent respray. Its clear to me repaint will always be expensive and continue to go up faster than inflation

Im really apprehensive about the car being fully disassembled. I just wonder if the 2 panels can be repaired / resprayed and blended with the rest of the car effectively?

Not all. My 914 race car was Dupont Imron, the same stuff they were using on many race car bodies at the time, particularly those that ran nitro. SS all the way and tough as nails. In fact, it was not recommended to paint over unless it was well roughed up and a full sealer/bonder/primer undercoat. Yes, you could put clear over Imron metallic if done within the time window. But you didn't have to.

What I know about painting Porsches is very small. There is (or was, no idea now) a guy way out in rural Oregon who painted with legit Glasurit paint. He wasn't sophisticated. He was detail oriented. He had a cult following. When my SC got smacked in the back, I took it to him. It shared a garage with a Ferrari. He welded in factory panels. Made it right. Painted with factory paint. I picked up my car and it was not detectable to my eye.

Take away? Ask the local community. Hopefully there will be someone nearby who is a little nutty about the stuff in a good way.

I've got a friend that runs a restoration shop and he's successfully done this for me a few times on some of my rescues.

Doing a respray on a roof on a 930 means you'll also do the quarter panels. If you don't you'll likely be able to tell, if you look close. Might kill two birds with one stone, for you.

The problem with a 911 or 930 is all the sandblasting the front-facing paint gets from typical driving. It becomes a case of, where do you stop? I imagine, you'll end up doing the rocker panels at a minimum.

A total respray costs a ton of money to do it right.

[javadog]

Here's a 930 that my friend cleaned up for me some years ago. The paint wasn't too bad but we did redo the typical areas that get sandblasted on a 930, along with the wheels.

The leather in the interior had been refinished multiple times (quite poorly, I'll add) and he was able to remove all of that shoddy work. The original leather color underneath was surprisingly pristine, as you can see in the photos. That's all original color, not touched up. No idea what suggested to a previous (idiot) owner that it needed to be refinished.

Lots can be done to sympathetically refresh a car if the shop knows what they are doing.

That is quite a lovely 930. I am sure it has appreciated a bunch since the sale.

That is what I am looking for some place/shop sympathetic. Good advice to seek out local expertise. I will definately do so. I am just trying to get in a bit of homework pre education to come into the discussions.

Yeah, I sold off my entire collection about 10-15 years early... Everything went up by a multiple of at least 4 or 5. Some days I wish I'd kept a few, like that one.

Ah well, you can't win them all.

Take your time with the due diligence. Good shops are hard to find; bad ones abound.

[908/930]

Quite sure being metallic colour of that year it is two stage paint. If there is still enough clear on the roof it can be carefully polished and re cleared after, but if they polish through the clear into the base coat then you start painting from base coat, that edge is will always show. Where the orange peel is could possibly be polished out, depends how much paint is on there.

Paint correction is a term that mostly applies to clear coats.
BC/CC is very forgiving; all kinds of sins can be fixed.
Usually, there is enough CC to wet sand/buff out all sorts of damage and scratches
Even with damge dwn to the paint, it is very fixable.
With CC, a very small area can be painted, like the size of a nickel! ( and CC over)
The whole panel need not be done.
As everything practice makes hard jobs more EZ.
It comes dwn to learning what wet sand up through the numbers means, and is a discipline learned.
This is my first paint job. Mistakes can happen

[afterburn 549]

My biggest mistake?
I welded the flares on and never used a bright light, vacuum, or air to check for pinholes.
I had to onje those, and it worked out even for a novice.

Not correct. Porsche did not use industrial coatings on road cars. Red metallic from the era was base and clear.

A good body shop can match and blend almost any paint. My 06 Vette has had the front bumper and hood painted and blended to the fenders. Nobody has noticed and I dont even see it.

[afterburn 549]

Yes
They now have a scanner that they set on the paint, and it will spit out the exact mix.

[Bill Douglas]

I got some silver paint a couple of days ago. I could get the scanned color code or I could pay a bit more and get a custom (hand done as well) match. I opt'ed for the custom. I'm yet to try it but fingers crossed they got it fairly right. Then it's the spraying of the metallic and how the flakes lay down is the next challenge.
