That seems a bit unlikely. The solvents quickly evaporate off. Unless you are soaking it in solvents, there won't be enough to cause any relevant effect. Meanwhile the helmet is exposed to UV light on a daily basis, which will also degrade it over time.
You are also not going to burn from briefly touching laundry detergent, but keeping lots of it on your skin would be a problem.
Helmets are usually polycarbonate and the common solvent in spray paint is xylene. Xylene causes extreme degradation in polycarbonate. If you don't know if the helmet and the paint are compatible, it's not safe to paint it.
Thank you. That is more specific than "plastic+solvent=bad"
Helmets are basically medium density styrofoam with a plastic cover. You ever spray painted styrofoam? It melts INSTANTLY ..
And you spray on the hard plastic cover, not the styrofoam itself
I'm not here to tell you what to do but most regular consumer grade helmets I've seen would be hard to spray the outside without hitting the foam especially near the vents... Foam which, once again, melts INSTANTLY when spray painted. Foam which is also basically the whole protective value of the helmet.
Anyways I'm sure there are helmets where it's possible to spray paint without damaging the foam. Or you could do a good job taping. Or you could shrug at the hopefully minor foam damage. Many helmets never have to protect your head so you might be lucky there too. All I'm saying is that there are good reasons to say "don't spray paint helmets" as general good advice.
Pretty easy to avoid if you use tape.
Depends on how many vents and how small they are. At the very least, it could be very time consuming to avoid while also still spraying most of the hard plastic. Would be easier to hand-paint.
Where did i say that? Between "Don't do this, it is lethally dangerous" and "it is a great idea, you should definetely do this!" is quite a large gray area.
Is it even gray?
"Too much water is bad for you."
True statement, like "spray paint will eat your Styrofoam"
Misleading though cause no one is talking about spray painting sttyofoam
