I'd personally like to see one done with a beam-axle in front and a buggy-spring quick-change in the rear. Add the wheels / tires from the Rat Roaster, and maybe the nailhead and Chevy engines from the '29 and '30 Fords (if they ever really come back). If not, include the Olds engine from the '50, or a 348-409 Chevy, or a Caddy. Instant period hot-rod, using mostly existing tooling. And ummm...try to get the stance right.
Since it's metal, you can use any real paint stripper (as long as all the plastic bits are removed first), and be sure to remove every trace of stripper. Any automotive-grade primers will work fine too. I prefer a self-etching primer directly over the bare metal, and then a sandable or high-build automotive primer for getting the body straight. Paint as you usually do. Again, even "hot" real-car paint is fine on diecast.
Anybody who's followed the old car market for any appreciable length of time should have noticed that car 'hot items' run in cycles, and "investors" typically follow each other like sheep to buy whatever is the latest-greatest up-and-coming whoopee-ride. Then, after everybody who has the money to pay stupid prices gets one of whatever it is... the bottom drops out. It happened to Ferrari Daytona Spyders, Mercedes 300 SLs, early Porsche 911s, etc. Folks who payed in the multi-millions for Daytonas can only expect a fraction of that if the cars are sold today. Using the same misguided reasoning that caused the housing market bubble that trashed the economy, people seem to think that prices for "investments" are going to keep rising rapidly forever, and they're somehow surprised when a saturated market suddenly goes cold. There just aren't that many people who can or will pay a million bucks for a Hemi-Cuda.
If you "transfer" your photos, they will disappear from every forum you have them on, and you'll have to go back and replace them all, one at a time, from the new photo-hosting site's urls...if you care.
I've been using P-bucket since 2010. It was free for several years, until I exceeded the free bandwidth allotment...because I was posting a LOT of build threads and getting a LOT of traffic. I now pay $2.99 per month for far far more bandwidth and storage than I'll ever possibly use. Where are you seeing the $399 per year? PS. I just checked into P-bucket and everything appears to be normal. You can only "post from (your) phone" here until you reach the photo limit, which isn't very large. You WILL need a photo-hosting site to store your photos, if you have a lot of content to display here. This is NOT a photo-hosting site, and they just don't have the server space to store everyone's pix.
Using a solid material, like nylon monofilament suggested above, would allow you to easily color it to match what's on your reference photos (most of the old "clear" hoses are translucent or yellowish). Adapting the fittings you have is simply a matter of measuring the OD of your "hose" material, and drilling the ends of your fittings to accept it....and this is a lot easier than you might think.
I recently bought one of the Testors version for about $50 (including stateside shipping) and one of the identical-contents "Circuit Wolf"-boxed kits from Japan, also including shipping for about $50...and that seemed to be about the best deal going at the time. Same kit, exactly
