Nice car Tom,
How do you get such a  nice smooth paint job on the 3D printout ?

Thank you Leo,

The short answer to your question woud be, time, patience and a lot of sanding during primer sessions.

This Oreca had about 6 primer sessions, I started with 1 layer/session and by the last 2 sessions i've put on 2 layers of primer.
After each session I had to wetsand the body competly, the first few I used a grit 800 and towards the end grit 1000.
I always waited 24 hours in between every handling I've done.
Primer - 24hrs - sanding - 24hrs - primer - and so on ...

After all of this was done, i sprayed on 2 layers of black (Tamiya pray can),
as the black would highlight the parts that required my attention a bit more
The rougher patches, luckely this time there were few to none visible.
A few spot of the turned out Flat a bit, something completly different the rough spots.
The flat spots will eventually go away as soon as the body gets a clearcoat.
But this time most of the flat spots will be covered by the Blue color that needed to on aswell,
this being "Mica Blue" from Tamiya aswell.

You might wonder, those are a lot of layers, (10 to 12), how much weight will this add?
We stayed just under 1gr. extra bodyweight.

It's a 2 week dedication process, but the result will last for forever!
It really is time consuming, but at the end it will all be worth it in my own opinion.

We are looking into faster and easier ways to get a 3DP body as smooth as this.
If we find a way, you will al get to know about it on the forum.

Hope to have answered you question.

Kind Regards Tom
