paint / ink you cant see with naked eye

[macafee2]

I am after some "paint" that cannot be seen by the naked eye.
I would like to be able to spray it on grass and not kill the grass else i'll spray on tarmac.

visible to infra red is good or visible by some other cheap method may do.

cant find what I'm looking for, can you help me out please?

thanks

Hi Ian - is this some kind of security paint?

[macafee2]

Darcydog will get this, most wont

sort of. we are still having trouble, been threatened with court action.
My son thought our response was and I quote "a great big f off in 4 pages"
We have asked for evidence and am hoping your car will be part of the evidence
If your car is used we will have great fun Trumping it. We want to mark the road or grass for our benefit but I don't want one and all to see it.

It as if we are playing Top Trumps, feel we won the first round.

Did you ever get a call?

Hmm I think your going to struggle to get something that is long lasting, so it tells if something and/or someone has been there in all weathers. Yet easy to see if you have a piece of detection kit that is easy to use and buy.

I can think of one or two things but you'd notice them and they aren't great to the environment.

Would cctv covertly placed not be a better idea?

not trying to record who parks where but to "show my family where to park"
does not need to last that long as could be reapplied. we need to see it.

You can buy sprays that are visible under uv light. Not too expensive but you'd need to apply a lot of it and it wouldn't last long outside in all weathers.
You can also get gels that would last longer but are more visible. Try looking at NDT websites/suppliers you might find something.

I was thinking along similar lines (no pun intended!) - would a strategically placed uv light then show the painted lines?

Not sure if such a light could be construed as a health hazard tho’ - seem to remember something about UV lights causing cataracts???

Have pm’d you Ian.
