Nifty Idea - Laser Paint Array

I don't know if this works, but I am proffering it as a nifty idea to be tested.  The working title is the Styx Laser Paint Array. This requires:

1. 4-5 laser reactive webs
2. a PS with a full load, and hooked up under the car so that if fired, it will put a paint cloud on the car itself.
3. a no-paint windshield (critical)
4. all of the webs hooked up to trigger the PS.  I think 1 link should take care of this; each array already costs a link each (as far as I know), and I'm rules-ruling that 1 is enough.

As you can piece together, the idea is that if any of the webs is triggered by a laser, the PS will fire.  PS (as opposed to SS) have 25 shots, so this will work for a whole battle.  With the no-paint windshield, your car will be unaffected (except for a constant paint bath; I recommend using glossy black), except if you have laser weapons - not a small drawback.

Total Styx Laser Paint Array system is: $2200, 75lb, 1 space, 2 DP =  (5 webs $500, 1 link $50, NPW $1000, PS $650/75/1/2).

Feedback desired.
