promo plastic from 1962 question

[62rebel]

i'm familiar with the acetate plastic used in the early days, and have a couple of kits and a couple of promos from the early '60's... i use rubbing alcohol to clean with and found that it actually acted as a solvent on my '62 Falcon promo... not horrible destructive action but definitely solvent...

am i going to be okay priming and painting this plastic or will i run the chance of crazing the plastic?

i generally use testors lacquers and enamel and tamiya spray, if that makes a difference.

another aspect is attaching modern plastic to the '62 plastic... i wonder if the standard MEK solvent i use will act equally on both surfaces? i.e., one side gets good melt on the contact edge and the other barely reacts at all?

i have a vision for my ancient promo but i don't want to destroy it trying to see it through.

The plastic that AMT went to for promo's in 1962 was branded "Cycolac", which we know today by its generic name, ABS. And yes, MEK will work very well with it.

I find that you can paint the Cycolac with hotter paints, even the Duplicolor cans, (but airbrushed) and they don't destroy it like what happens with styrene. I've restored several promos that way.

good! now i can set about slicing and dicing a fifty year old promo..... well; first order of the day is removal of some trim that doesn't exist on my 1:1 Falcon..... working out whether i can scratch a substitute interior tub so i can get some better detail in there, and contemplating modifying a spare ranchero chassis heavily to get some decent chassis detail AND then possibly scratching up an engine bay and slicing open the hood.... i got the best reference source available, the real deal out the back door.
