The paint finish wasn't uniform enough- glossy and less so in areas. I'd like to prototype a windscreen in acrylic, but I don't think I'll be able to get it quite right and like you say it may look too yellow when finished.
I'm adding the side strakes in just with strips of styrene, fiddly task! Again milling them would take very small cutter, and a lot of time.
The CAD body was made in a series of panels, then I 'filletted' them with the basic tool.
I guess the picture didn't really show the uneven finish like you explained it, but not to worry some abrasive paper and a bit of polishing fixes everything haha.
Those side strakes are indeed going to be fiddly work and I imagine a few bouts of curses whilst cutting them, good luck with that.
The fillets look really good if there only the G1 type, sometimes they can create strange reflections though. G1 fillets have only a single constant radius across the entire curve, where as G2 and upwards, when viewed as a cross section, are more like a spline, and do not have a single constant radius, but a varying radius, or varying level of curvature. With software like SolidWorks, which is what I use, you can't set the curvature continuity to G2 with a basic fillet tool, that will only do G1, but you can create G2 type lofting through spline profiles that are curvature continuous to your 'master' surfaces. Software like Autodesk Alias have a 'blend' tool which can to G2, G3, and G4 type fillets. The higher the number the more your surfaces will look like a single continuous body.
G0 - Surfaces meet without tangency.
G1 - Surfaces meet with tangency, but not curvature continuity (continuous radius fillet).
G2 - Surfaces meet with tangency, and with curvature continuity.
G3 - Surfaces meet with tangency, curvature continuity, and the rate of change of curvature is equal at the point where the surfaces meet.
G4 - Surfaces meet with tangency, curvature continuity, rate of change of curvature is equal where surfaces meet, and the rate of change, of the rate of change of curvature is equal where the surfaces meet.
Typically all automotive class-A surfaces have at least G2 continuity, and more and more these days, this level of continuity or higher is even used in interior surfaces, not just the exterior alone.
Thanks Ikocev, when I designed this car, I didn't have the tools to do all those blends. I understand them now and use them more.
Model update, put the side strakes in, not to difficult. started painting all the black and white surfaces. Starting to look real now. Once this is done the interior is the nice job.
Fantastic job. Want tips ? You give me some tips ! And some talent too lol.

I have put in the floor and seats of the interior together now. Also added the roll hoops and exhausts. All that is needed now are te wheels, decals, and mesh in the rear vents and front grill. I am quite pleased with the shine of the red colour
Hi guys, car is finished. I'm happy with the paint work, it's really glossy. If I was to do it again, I would take the time to make the slates in the side the correct profile and curve with the main body. As for the design, it's too long. The mid section needs to be closed up. The front and rear overhangs I like. Overall the design is low and wide and probably closer to a F1 car than road car! All I need to do now is some fanboy photoshop images and get someone to invest in a fullsize working model!
