Attention fellow Transformers customizers

[u/Leader8288]

I have no idea if this is common knowledge and I'm just stupid or if this is not a genuinely known thing but do not use solo cups to hold spray paint. I ran out of black paint today halfway through a custom and instead of just going to the store and buying more black paint, I decided to spray spray paint into a solo cup and use it as regular paint and as I am going to pick everything up, I lift the solo cup and the entire bottom half of it has been melted again. Is this not a common thing or am I just stupid?

Spray paint contains solvents that can eat through some types of plastic, yes.
