Subject: Problem Stripping Primer with Super Clean
I'm having issues getting black primer off some models that I bought.
1. I soaked them in super-clean (the purple stuff) for a week.
2. I watched this video.
3. I got an electric toothbrush and a regular toothbrush.
4. The superglue bonds broke (which is fine).
5. Paint came off the individual model pieces just fine with the electric toothbrush.
6. Primer will NOT come off with the electric toothbrush.
7. I can scrape the primer off with a fingernail - so the Superclean must have softened it up at least.
My initial thought was, "Well, I need to get a wire brush to get the primer off." In the video above, it doesn't take any of that work. I don't know what these were primed with, but they were primed black and I need them returned to plastic grey so I can prime them white.
Get an ultrasonic cleaner. You can find them for around $40 (last time I checked) and they REALLY help get the stubborn paint off. I've stripped enamels from plastic before, no problem.
Well, a little problem, but less trouble than you seem to be having.
I have had this happen with super clean and certain primers even while using an ultrasonic cleaner. Some primers are just more stubborn than others. I would just repeat the soaking with fresh liquid. It will eventually remove it sometimes it just takes longer. Some primers will stain the plastic as well.

Can you recommend a good one?
I've been using an electric toothbrush, then a brass brush. It's killing me.

Is it obscuring detail, or fuzzy? If not, why not just lightly prime back over it? (Serious question, not some rhetorical one.)
These models are all primed black. They're going to be angry marines (yellow and red) so they all need to be primed white. The black is also pretty thickly on there. I didn't want to white over black, so I'm trying to get them to grey so we can restart on white.

I use airbrush cleaner from Revell.
It`s super agressive, cleans of colour + primer in no time with almost no effort.
I once cleared an khemri sphinx with almost all details gone due to too much black + gold primer in about 15 minutes.
Safe for plastic, haven`t testet it on resin though - just as warning.
It is a lot more agressive than other airbrush cleaners (according to an airbrush using friend), so you might wanna stay with this one. Of course i have not tested other ones so there might be an even more effective product.

the ultrasonic cleaner you bought should work just fine, i have a similar one. get some hose for the valve and you can put it on a table, fill with super clean and then empty the old fluid right back into the bottle it came from when it needs to be replaced.
