POLL: How dangerous is my custom painted helmet?(7 posts)

POLL: How dangerous is my custom painted helmet?Mr Nick
Nov 10, 2003 1:17 AM
So I got a lot of flack for painting my Bell Furio black with Krylon's new "plastic paint". The concensus was that I probably hurt the styrofoam in some unseen way and that if I every crashed I am going to be sorry.

With that said the next question is:
If you were in my position would you spend the money for a new helmet? I can get the Bell Furio '03 in black from Performance for $59.999. So is the possibility that there might be unseen harm to the foam worth $60?

This is a serious post because after all the negative comments I am a little freaked out. So I appreciate any opinions.

it isn't protecting anything important. :)

You obviously have doubts, it is going to be lurking in the back of your mind and ruining your rides. Get a new helmet you cheapskate. :)

I'm sure that absolutly NO UNSEEN damage have benn done.
I guess that inner part of foam doesn;t differ outside part and so if outside part that has direct contact with the paint doesn't protrude any damage in which magic way inner foam can be affected?

BTW, I guess that repainting helmet from yellow to black (or other dark color) wasn't very wise as yellow is much more noticable in the traffic and so more safe.

Get a new helmet and don't paint it.

The paint solvent will indeed ruin styrofoam. Experiment: Make a cup of tea and put a lemon wedge in it. Leave it alone and watch what happens at the interface. The lemon oil will eat holes in the foam.

More dramatic: Take acetone, paint thinner, whatever is aersolizing your paint and put a styrofoam cup in it. 1-2 seconds later it will be gone.

That could be your noggin. Not too reassuring, is it?

Are you riding with a bunch of chemical engineers? How exactly did the paint harm the styrofoam?

Unless you painted the styrofoam itself, with significant coverage and thus a large amount to soak in, it's fine. IN fact, if there was a problem, the styrofoam would show damage in the form of dissolved areas or the appearance of melting.

The Arizona sun you ride in does much more damage to the styrofoam than incidental spray paint vapors would ever do.

Painting the foam liner can only add strength, if only a tiny bit. I crashed in my old Bell V-1 Pro a couple of years ago. Previously it had taken several hits, was run over once by an SUV, and although the shell was still intact, the foam liner was cracked twice on one side.

I went over the handlebars and hit the curb. Although knocked out, I regained awareness in about two minutes, standing up, holding onto the bike, asking the concerned guy peering into my eyeballs how long I'd been out. Hospital scans found nothing amiss. The cracked helmet had done its job.

Now I have a new helmet. The doctors said helmets will prevent concussions only to a point. When the head strikes something hard, the brains get jostled under the skull and the rider gets "knocked out," even as the helmet absorbs the shock of impact and prevents the skull from breaking.

This is just to add a little perspective on the subject of helmet safety and when to replace them.
