would a puddle look good on a tank? like right after it rained?

I guess, like anything, it depends on how it's done. It might be more effective if part of a diorama so people get the sense of rain, or else people might mistake it for oil, gas etc. I am just wondering where would you put it and would a puddle have time to form?

I dont see why not. I think to show this you would have to use gloss paints and to cover the entire vehicle as if it was raining you might need to show more to achieve the effect ... like soldiers sheltering from the rain. But as the tank started to dry up there would be puddles left. This could be made by painting the puddle by a few layers of gloss paint and have some leaves floating around the outside.
This has just come to me ........ Sometimes when you use the wrong thinner it breaks up the paint instead of thinning it ...... using a wash of this around the outside of the puddle to show washed up dirt and grease etc. I have never tried it but it could work!

Hmm... a puddle would look okay if it were say collected in a low point of a tarp on a tank, but that's about the only thing I can think of...

I'm with gunner on this one. The surfaces would be wet, but the tank would not collect puddles and if the vehicle was running, even idling, the heat generated would dry the engine and exhaust areas quickly after the rain stopped.

100% agree with Gunner and Rob. It never happened to me to see puddles on the tanks I've been on even during the worse thunderstorm...

If the tank were at an angle, there would be a puddling effect in some areas. Of course definitely on a tarp. To do this, I read there is a new product out called instatnt water or real water. Already mixed you just have to pour it. I think it's by theWoodland scenics company. Read about it here. someone used it in a Viet Nam diorama.

I saw that dio thanks now i know a puddlwe wouldn't be all that great on a tank
