question!?!

I would use a medium gray sandable primer myself. Defects will still show up very well and it won't be quite as hard to cover.

Enjoy your modeling...

It will also work if you use flat black as primer. You can sand it, touch up by airbrushing patches, level it out to perfection & everything before painting it with the gloss metallic black. Plus, it's likely to end up a much thinner coat than primer would be. Don't wanna obstruct any of that car's detail with thick primer, right? Flat dries fast, but give it a little more time to dry than you would primer to avoid crinkling. I'd use a flat black that matches the metallic gloss black: enamel, acrylic or lacquer. If it's enamel, think about airbrushing on MM's color called "black chrome trim" as primer. It's satin black. I have no idea why they call it black chrome trim.

cool thaats what i thought, ill go get some flat black spray 2moz.
ive tries out using el cheapo automotive spray cans as primer and it seems to do the job really well. like u said its thin and it leaves a nice texture on the model... and the cans r cheap as chips (2.95 from super cheap if u live in oz). ill keep u guys posted as to how it goes (getting my paasch h on wed!!! woohoo!!! i wanted a badger anthem but its too expensive. but i needed a quiet compressor...ohwell...)

some (almost all) spray can paints in the US will attack model plastic. You test it out on wrecked models first, right?

ya of course! i bought a stack of 1/144 planes 4 that :)
so i got some paint and painted 3 light mist coats ( just covered the car..i need practice still) and let it dry. the paint then felt kinda dusty.. asif when i ran my fingers across it was coming off. then i got a mesh scrubber for the kitchen, its non scratch, and rubbed it down and got a nice finish. then i got some toothpaste and a brush and brush it down... now i got a smooth finish overall...
its a shame i havent used tamiya primer so i can compare it to but i like this stuff..
i also rubbed some tamiya compound to compare it to tpaste ( and rubber through a bit god damit!!!!) and the finish feels the same as the tpaste. can anyone tell me which is finer? tpaste or tamiya polishing compund?

btw the paint sis australian export gloss enamel (even tho its matt!?!??) it didnt say anywhere on the back that u couldnt use it on plastics so i gave it a shot...
gota say im happy with the results..and u cant beat the price!!!!
