Hi Stuart:
They can be sanded off or cut off with sprue nippers or a razor saw. Biggest thing is not to screw up the good stuff around it.
You can also use a Dremel and a ball shaped bit and grind it down that way

My condolences. He as all every one said and when I was Prez he helped a lot with ship questions and other things. Plus he put on a great convention in OK. City. He will be missed

I too started with a Minolta SRT201 in photo class. Still works 40 years later. I use a Nikon D3500 now. Used them for 500 reviews here in IPMS
I will say having a good photo background helps a lot. I bought several off Amazon

OK, see f you can try this. I have an outside window. I connect the spray booth to a square/rectangle of carboard and put it in the window when i paint. You can add a couple handles to make it easy to move. In bad weather, I seal it so I remain warm

And for what it is worth, acrylic paint are far, far from benign. They contain alcohols and all sorts of additives. And if you spray anything at all, you need a spray booth
