The air eraser comment was directed more toward you Alan. Don't you remember using yours to strip some of my old Rivarossi cars? I think we both got more on the surrounding bushes than the cars themselves. I think we both do a lot better now.
Believe it or not, the best thing I've found for Rivarossi passenger cars is Scalecoat stripper. The first batch of Scalecoat I tried on Rivarossi cars many years ago, must have been a bad batch, cause I was given a new pint of it several months ago and it worked extremely well!
Those RR pass cars I posted several months ago were stripped in it in less than 20 minutes.
Its not really the changes in the BF so much as the changes in the plastic formulas, and we wll never know what those changes are. Don't know if you 'member or not but right after I taught you the "proper techniques of airbrushing",
(which you seemed to have successfully butchered BTW) you showed me your BF tray, I said then not to use the BF on anything that was plastic. I swear, Eyes buy yo' books and send ya t' skool an' ya still don' larn nuttin!!
Really thou, when you have to try and replace two shells that haven't been available for years, (Atlas\Kato RS-2's) because the Brake Fluid brittlized the shells, you don't take any chances. Especially when the damage did not show up until they had been sent back to the customer.
This was before the internet, (early 1987), and it took me months to find a hobby shop that actually had them.
I do use denatured alcohol not isopropal, to strip plastics and except for Rivarossi, and Kato, the DA handles everything else quite well for me. It get things that iso won't touch, Grasshopper!
Really, if I could afford it, I'd just buy some Chameleon stripper. But until its price gets way better, I'll stick with the denatured alcohol.
