Repainted Roundels

[wcl4]

Repainted my C pillar roundels. For anyone who might have done this in the past, what do you spray on as a protective coat so that they don't get ruined with a car wash, wipe down, cleaning product, etc? I used some spray paint from the auto store for the black and the white and Testors for the blue. The paints seem to dry weirdly when they're mixed and matched like this.

I don't know what you should clear coat them with, but you will need to make sure it is compatible with both the spray (likely an acrylic) and the Testors (likely an enamel). But they LOOK GREAT! Nice work!

So Testors doesn't seem to take well to coatings aside from their own clear coat which is quite thin. In my quest for roundel nirvana, I tried a new paint today called Rustoleum Sail Blue. Not sure how well you can see it, but on the c pillar jpg, the bottom right blue is the Rustoleum with the top left being the Testors. The hood is what I have as the benchmark. The Rustoleum is a bit redder in value, but is actually closer in shade to my hood roundel, albeit a bit darker. The advantage to the Rustoleum is that there's a clear coat product that hopefully will protect the finish better than the Testors clear coat.

Traditionally, clear lacquer was used as a protective coating on many things including brass to keep it from tarnishing.
You would just have to test this on the paint you are using on something other than the Roundels.
Shellac is another protective coating. Hard to find in a really clear form. Usually a little yellow to red.
Clear lacquer is available in spray cans. I think MinWax may make this?

I tried the Rustoleum clear enamel coat, and the white took it fine, but the blue curdled! I don't get why paints from the same brand with seemingly the same formula (gloss protective enamel) would not be compatible with each other. *sigh* At least the Rustoleum is considerably harder than the Testors.

Yes, I hate when that happens. Aaaarrrrrggggg!
Try this. Read what the can says. I know the Dupli-Color paints have a limitation on the repaint time. The time you have to apply more coats. I forgotten and applied more the next day and yuck it turns into a mess and have to start over. Just a thought.

 

[wcl4]

It was a good idea. The can is no help. Just says some other lines of paint are not compatible with the clear coat.

Well after numerous tries, this is what I ended up with. The sail blue Rustoleum is in the color family in my opinion, and has advantages over the Testors in durability. The original seems more turquoise-like whereas the sail blue is redder but a bit darker than my hood roundel.

have you tried the paint that was previously mentioned on the forum - sign painters' lettering enamel 154-L process blue

 

[wcl4]

Is that available in a spray can? One of these days I'll have to invest in an air brush. Damn, I may have to give another go.

 

[deQuincey]

that blue is not correct , but the result is very good, have you been masking once and again for each colour ?
i used the light blue from rustoleum and it is very accurate like the original
nonetheless you can consider it done with that blue too, it looks very nice and you usaloy do not compare one with the others so close

 

[wcl4]

Yes each color is masked. It's much more difficult than what I had anticipated because at any given stage, if the tape touches the paint, it can ruin the finish. If the tape does not make a good seal, there could be a bit of overspray. If dust falls on the paint during drying, that causes issues. A lot can go wrong.

i was looking this up and whoever i got this information from has 2 different colors mixed up. 154L is peacock blue and 153L is process blue. has anybody actually repainted their roundel with one of these colors and found a good match?

Scott, After much trial and error I got one painted to my satisfaction.
I had to mix the blue to get it right. I have "formula" in the paint stuff.
Biggest problem was getting the paint to lay down and be smooth.
Spray with white was ok but had to brush the blue on. There are some tape tricks I can tell you about from my woodworking days.
Finally I went after it with the buffer after is sat for many weeks and cured. That smoothed it out.
There is a guy out there that will refinish but at $250 I turned cheap and was determined to do it myself.
Be glad to show you what I did.
Gary

thanks Gary, i am working on a new FAQ post on what to paint on the coupe ... in what color. and this blue was one of the last things. when i searched what i had previously been given i found it was conflicting. so i'm trying to sort it out.

There is not one color that is perfect for the blue. Close and unless next to another Roundel you might not notice.

Has anyone just taken a roundel into a commercial auto paint supply and have the match it? They matched my viper green 911 paint to the T and that color is a pain to get right... Just a thought

the problem i see is, over the years, the roundel blue has changed. its now a tiny bit of red, creating a purple tinted blue (lilac), previously it had a little bit of yellow in the blue - very slight teal. my old roundels are too worn to use (too little blue left)

here is my curiosity - to somebody with a really good original roundel. how does it match with the blue color in the cloissonne roundel?

here is a newer one
