Artificial outdoor water

[captain perry]

I build wood-epoxy kayaks and have access to some pretty cool epoxies...they are expensive and NOT UV resistant, I do not know of any that are.  Whatever you use will probably yellow with time and loose its shine

perhaps a piece of window glass?

Have you looked into Fiberglass resien, the type used for Boats thet should be UV resistant .

I’ll join the choir with why not use real water? It scales very nicely. I have found a resin that is both UV resistant and temperature proof, made by “Fahrbarhard” but at just over $20 per quart, (plus international postage) anything larger than a small stock pond is too expensive.

 

If you are after something like water spillage from a pipe (culvert) then why not do something cheap that is easily replaced yearly. Twist some clear tape and cover with spar varnish.

Us indoor railroaders usually use two-part resins to model water.  The usual stuff might not hold up to large temperature swings and UV, but perhaps some stuff that is designed to work with fiberglass, say for boats or something?

Resin takes a long time to cure, and it stays "wet" for a long time.  During drying, it will need to be covered (though not touching) to keep dust and dirt off it.  Each pour should be no more than 1/8" thick, so it will take a few pours to make a G scale water feature.  Tinting the resin can make a water feature seem deeper than it is.  Usually, each pour has less tint than the one before it, with the last pour being nearly clear.

Since you're doing it outside, why not make a real water feature?  I've even seen some indoor HO layouts with running water.

Ahhhhhhhhhhhhhh uuummmmm.....not quite sure what you are asking, just what is it you are proposing to do  

Why not just use a real water feature

Anybody have ideas on how to make artificial water that will stand up to being outside??
