Obviously Jim you have been ABUSING...
the emblems as well as the car.
You should be taken out and lynched!
And I agree with Bob (please note... as these agreements are rare...) that Testor's was and still is my favorite paint.
The also make PAINT PENS as well but I think a SET of Red, Black, Yellow and GREEN (probably Blue and White as well) and a few brushes would work well.
Something like this here for less than 10 bucks:

And CLEAR enamel spray as the topping!

As for "technique"...
I would "pick off" and remove ALL the remaining color and then CLEAN the it all with LACQUER thinner and then ALCOHOL.
The RUB the entire piece face down to ensure there is a high gloss on the RAISED areas. I would NOT bother to use Primer... as you are gonna FLOAT a lot of paint in the recessed area as if it were a "porcelain" filler.
(I believe the extreme COLD there caused this problem... we have FADING issues here...)
So... No that they are cleaned up and ready... float a lot of paint in the recessed areas doing the smaller areas first. Let it dry and shrink for a day, and keep up the process until you have the level and quality you want.
Clean up the HIGH's just by rubbing face down on a cloth on a hard flat surface. I doubt you'll need it... but you could use a barely moist cloth with thinner and rub LIGHTLY, and then rub some more on a dry cloth. FLAT COTTON, no terry or microfiber!
Now... apply a light coat of clear and let it dry for a few hours, the several more allowing them to dry thoroughly... BUT do this all in a matter of 6 hours or so.
If you wait a day or so... then you'll need to wait about 2 weeks before attempting it again as it will either tend to FOG or otherwise impact the paint below it.
Have fun, keep in touch and take some fotos... and unless you find a better way to keep your car in a more moderate temperature, this will probably happen again.
Lastly, my daughter is a damn good attorney and we could go after Ricardo and sue for a new set plus the pain and suffering you are going through. All you need is your Warranty Card and Receipt. You do have those, right?
(hehehe!)
