Has anyone used them as goooooo? I just got a few cobra bodies and I want to try to mold some real wheel wells on them. Basicly does the testors cement work on these too?

So mant projects so little time! LOL

T-Jet, I cant say for certain, but here's what I do know.

If they are painted you'll have to cut it back to the white parent plastic or strip the body, make your mods and repaint. Any residual particles of paint will generally reappear in the worst possible place, like dead center in your new flares!

Try striping off some paint on the underside and rough it with some 1200 so it dulls. Then give it a light reglaze with some testor's. If a nice shine pops up and it doesnt get over mooshey, you should be good to go.

Though, as you know and for the record, I've had some plastic react badly to "testors abuse". I always take the time to do some test shots before I go whole hog. Of all the batches I've cooked up, I've had three go weird on me. A batch of black, made from a later version more flexible Tuff ones Lola, a batch of yellow made from a daredevil ramp, also the more flexible "tie it in a knot" plastic. Also the batch of white used on my latest Indy Nosed Deuce was making me a bit nervous, but it did work out fine after all. ( It just looked weird I guess) The other two did NOT provide the correct results!

So all that said, if you can bend the parent plastic easily without snapping it, it's probably a no go. If it feels like it's gonna snap and cut your finger or poke you in the process, it'll cook up fine. Another indicator is how the plastic fuzzes up when you use the cut off wheel. The good stuff will leave a ragged fuzzy trailing edge that crisps up fairly quick and will scrape off with your nail. The wrong stuff will leave a lumpy bubbly looking roll that takes more time to get crispy and feels rubbery.

My final test is the sound the plastic makes when you tap it with a screwdriver or file. If it makes a high, clear, "Tink" sound it's good to go. The duller sounding "Tunk" or thud sound is the stuff I try to avoid. Which of couse is not to say that it wont work, but it is a warning indicator.

Note: I never mix styrene from two different eras or manufactuerers in the same batch. It's not all the same stuff.

If after a 24 hr cook, it looks like a greasy blob of mayonaise then your on the right track! If you cook it up and after a quick stir it still looks like cottage cheese toss it out! It's not right.

Not very scientific, but it's all I got! :wave:
