Just dipped an old AMT '29 Model A roadster body. Had a few questions but lumbering along on my own, figured most of it out my own self.
#1, Found a little plastic tub just big enough for the job.
#2, immersed the body with enough Purple stuff to cover it.
#3, left it over night, 12 hours.
#4, rinsed it off in the sink, with a little toothbrush action.
#5, Wiped her off, lookin at one pristine piece of plastic.
?#1, How long to leave it in the pond?
?#2, What to do with the Purple stuff when done? Figured that out myself, amount used vs amount purchased insignificant, @ $ 5 / Gal. at Walmart, down the drain it went.
?#3, what material tub to use? So far so good. Probably wont use the good Tupperware.
