For painting the tail I would recommend Krylon Fusion based on what I've read and what others have told me.
well it was just kind of figuring it out as i built it, i attached the top the car, then bottom to the car, then those to the little rectangle at the tail. i diagonally cut the third 4x8 sheet into two equal opposite triangles attached those to the top sheet and worked and molded them down then attached them to the bottom piece.

looks good, I think the angles on the top side of the tail are a bit steep to start with then get to flat, but is better then nothing.

Can you open the hatch?

Any way to tuft test?

do you have any goodies at work that might make testing easier?

the hatch is INOP at the moment i did the tail without much planning so that will be my next mod.

tufting, havent gotten around to it but i really need to, to address the overly steep initial angle.

no goodies. although a community wind tunnel would be nice!

I think the angle where it starts coming off the existing hatch line is about the same as the hatch slope. So it's probably good. Looks like the slope is more level after that, probably is not as steep as what you could get away with.

Just my guess. Would be nice to see if we can get aerohead to comment.

The CRX rear hatch gets attached flow, which should mean you can at least follow that slope down. You can probably even ease it down to a steeper angle. I noticed that your side profile shot is actually a little bit from above. You might get better use out of the template if you take a picture from about the height of the bottom of the window.

The video's been taken down, but you can tell from the ensuing thread that it was attached. http://ecomodder.com/forum/showthrea...lass-8097.html

Welcome! Nice car! Good advice already posted. Enjoy.

I sent aerohead (Phil Knox) a pm pointing to this thread, and included the profile photo in post #14 above. He pm'd me back, so here's a paste of his note for you.

I think your slope is okay.It looks like it continues down and back from Honda's curvature and they spent a lot of time developing that roofline.
The length of the tail should force the air to behave itself and your diffuser angle looks like your unlikely to do a ground strike when going up and down driveways.
I'd like to be riding shotgun when you test it!I think you'll be smiling at the gas pump.I just recorded one of my best mpgs with the boat tail on the T-100.
It really gives me a charge when members stick their necks out and go for the gold ring.
I appreciate what you've done and for including me in your circle of maniacs.Let us know how she shakes out at the gas pump.Thanks again,see ya,Phil.

ill definitely keep posting mpg numbers, this tank i put on my air dam. the funny thing is that with it on i have to get it up to 70 to get good coasting. 65 or below the speed drops off quick. in short at 70 i hold my speed longer than at 65. this only happens with my air dam on .

Sweet car. I'd say hack that boat tail apart and make sure it's all 15* angles! For tuft testing get somebody with good eyesight to stand on the side of the road while you drive by at 25mph. Keep it up.

one of these days i will hack it down to proper size but for now the eccentricity of the car is fun. I just put a nose that looks alot like basjoos's aerocivic. i'll post some pics tomorow, but it is crude and i just wanted to see if I got good results.
