Hi all experimental film fans!

I have several reels of 35mm films and iˇd like to destroy them and make my first analog movie, but i have no experience with it. Ive tried vinegar and baking soda, but it doesnt work what i want. It good for scratches with needle. I want to make similar like this:

Can you recomend me which chemistry can i use? Or which type of colours for paint on 35mm can i use?

Thanx a lot
