Paint Remover? and Wobbly Wheels

Just how hazardous are we talking about here? And what is PPE?
And @Nigels, I'm using Americana Gloss Enamels now, but the paint I had used on my Plarail Toby are just normal acrylics. Today I just finished cleaning my room(s) so I can't go back to check what the brand was that I forgot, but many of the acrylics had a big, red apple in the logo.

Well not hazardous enough to kill you or permanently damage you, but hazardous enough to wear gloves and eye protection, gloves especially if you have sensitive skin! I'd hate for you to get dermatitis because of it!

This was the video I watched,

Basically submerge you item, leave it, remove and scraps. it's been working great for me,
