In Progress - Ferrari F355 (again)

[CADguy]

Some of you may remember this car I completed about a year ago.

About 5 or 6 months ago I went to a model show, and noticed that the clear on this car had cracks all through it.
I thought it was that I sprayed Tamiya clear on too late. But after looking at my progress thread I realized that I used Cobra Colors clear on this car, so that couldn't be the case.
While stripping it I discovered that the cracking was not in the clear, but all the way below the paint in the primer.
I primed this with VX primer by Cobra Colors, then Duplicolor white primer, paint, then clear.
The Duplicolor was where the cracks originated from.
I know some Cobra Colors customers use Duplicolor primer with success, so it must be a problem with my process.
My guess is that I did not allow the Duplicolor primer enough time to gas out enough before applying color and clear.

I could not get a good pic of the cracks before I stripped it in 91% alcohol. But during stripping, they were quite visible.

Some filler, I knocked out while stripping, has been replaced with superglue. She's now ready for a new coat of primer.

I never really was crazy about the Verde Zeltweg Metallic paint I used originally, and wanted a lighter green.
The color I wanted is now available from Cobra Colors, so i will use it. It's Verde Mugello, a slightly lighter green.

My order of Cobra Colors primer should be here today. I'm anxious to respray this car.

Good luck w/the respray! The model will look great in that lighter shade. That's the color I thought it was going to be in the first place.

How long did it take the 91% to strip the paint? I'm still seriously thinking about the 612 hood redo; Polly S Easy Lift Off did the job in about an hour or so before w/many layers of different paint including Acryl clear.

Thanks, I need this repaint to go well, to get me motivated to work on those Dinos.

I let it sit for about 2 hours in alcohol, and it came of with ease.

I remember this model! Beautiful work, as I recall. Strange thing, those cracks appearing so long after it was finished. However, the new color is going to be beautiful, so I look forward to the finished pics!

Great recovery!

I've got the same problem with my Tamiya's Evo VI, Fujimi's Dino and Revell's BMW. At first I taught it was just the clear cracking but when inspected the crack starts from the primer. This is all caused by trying to finish building a model in 5 days Now I let the model for a week before another coat.

This is going to be yet again a great build from you...

Always frustrating to have to strip- especially on a long finished model.

You had me worried for a minute there- I hadn't heard of CobraColors clear or primer cracking. Using CC's new primer, or the old VX again? I'm curious to know how the new stuff works, and what color it is!

Do you have any pics of the Verde Zeltweg in a bit more light? I'm considering it for a 360 (it looks great on the CC site), but I'm suddenly worried it might come out darker than I want.

Good luck with it- looking forward to seeing the new color.

About 80,000 to 120,000 USD, depending on model, year, condition and milage.

MPWR-the new primer is called Moon Mud and it's a typical light gray. It covers a lot faster than the VX, it's pigment is much more dense. VX is a good primer and does help seal the plastic, but not against heavy duty applications of clear lacquer as I'm prone to doing

I concur that the biggest paint problems like this are from impatience and not letting underlying paint coats dry long enough, I know because I'm still dealing w/it on one of my cars

[Wheelin75r]

That green looks verry nice!!

[MikeWz]

Good luck! That color looks excellent on that car and cobra colors look wonderful so that model should look stunning (Especially because it's an F355 )
