[Lid Removing tool for stubborn paint]

Cut the bottle, and move the paint to a new one. If you've had the problem once, it will happen again many times. When you change the paint bottle, if it is acrylic, add a few drops of paint revitalizer to recover the paint a little.

["Chipping" color.]

Do you mean what color? red and orange as the base coat randomly applied, then any chipping medium, and finally the color of the model.

Then use a scratch brush to remove the surface paint and expose the rust-colored red and orange primer colors.

[Using Paint masks]

I tried the vinyl mask and it didn't work for me. The glue was too weak and the paint went under the mask.

 

[Diorama guys help needed. Clay won’t stick to base.]

You should place some pva glue in between both, and let it dry, they should stick

[Any ideas on using decayed / dead decals ?]

If you have a printer, and you could also get some decal paper to print them again

[Ca glue undo]

Well, you have a big problem in front of you, I've been there many times myself. I have tried several brands of products to remove cyanoacrylate, and in the end, I have stayed with this ciano glue debonder that I've been using lately, and I'm doing very well.

[91% ISO as a Stripper]

I use this paint stripper to remove the paint I want to remove.  You have to submerge the plastic or resin part partially in a jar with a lid. You have to wet the whole part, but only cover 10-20% of it, and leave it for 30-60 minutes. Then with an old toothbrush the paint will come out by itself. The product is reusable many times so the 240ml lasts a long time. The smell is almost neutral. It works quite well in general.

[Old Paint]

I have recovered many old paints with this paint revitalizer. It works quite well.

If the paint is solidified, it does not work. It has to be acrylic paint and with some moisture.
