As much as I hate telling you that your idea is great, it is.

I won't know until its warmer here and I drive the car but I'll find out how exterior urethane and gloss rustoleum hold up in the elements.

It holds up great.



I've done two fulls day in the rain now, and no warping, sogginess or apparent absorption.

I use West epoxy for anything CF (including the CF on my splitter) but if you're just doing the standard 'glass (or simply a coat of resin without glass) baller epoxy is wasted there, poly will do just fine.

If all you want to do is waterproof it you're wasting your time with wet layed reinforcing cloth. I would put a coat of Kilz on both sides of your plywood, and rattle can it the color of your choice on the bits you can see. If you want to get fancy, you could try a two part flooring epoxy. I bet your local Sherwin Williams would give you a sample of it big enough to do your splitter for free.

I have also used polyethylene rub blocks on really low cars before by countersinking the PE, pre-drilling the holes, and cutting off stainless self-tapping screws to ~1/8" short of punching through the plywood. You can get PE strips from McMaster or US Plastics, or slice up white plastic cutting boards.

What is kilz? Just googled. Cheap and looks to be effective. Got a 12x12 .375" HDPE sheet of amazon for $10.

Doward, link to the stuff you used?

I painted the whole car with this stuff

Shop Rust-Oleum Professional High Performance Gray Gloss Oil-Based Enamel Interior/Exterior Paint (Actual Net Contents: 128-fl oz) at Lowes.com

It's far from a specialized solution, but has worked long enough to outlast the splitter itself. I've damaged it enough to need a to cut a new one. I'll be painting it the same way again.

Hey gents,just looking for some opinions on whether or not how I've mounted my splitter should be sufficient. The front supports are bolted to existing holes in the bumper beam,the brackets I made are supporting the outer edges and the rear is held on with flat brackets and the small bolts that hold on the rear of the splash shield. I've been thinking about adding a few more to the center. (This is an old picture as well,its since been urethane'd and painted gloss black) Thanks!

It ain't DIY, but I thought you'd want to see what DG Motorsports has just made. Dave Green builds the tops that are sold through Mazda, and he also sells through 949, Goodwin, FM and direct.

Pretty sure I wasn't even supposed to show anyone. It's just too freaking beautiful. If I bought an ND, i'd buy that hard top too, just because.

Other way around here: now I want an ND just for that top if it clears the Blackbird GT3 bar

It was designed around the GT3 dimensions, so you'd hope it fits... it clears the RZ bar with inches to spare.

Oh I DO hope, I think it'll greatly boost the sales of the ND GT3
It just seems to me like the peak might be a bit too far forward, but I'd love to be wrong!
I'd expect it to clear the RZ by a good margin, but the GT3 is much bigger.

Default BFW ND GT3

It's not just that the GT3 is bigger, it has a slight tilt back to give taller drivers more room (can you guess why? ) -
