Will stone-look spray paint last outside?

Question

I have a metal roof of my tiki bar outside. Want to make it look nicer. Too expensive to purchase grass/palm thatch to cover it (like $250-$300 because it's large) so I thought of buying that spray paint that makes the surface look like it has a rough sand exterior. Will that last outside in the rain?

Answer 1

If the paint is rated for out side use it will

Answer 2

If you have a good application it will last quite a while. Make sure your surface is ready to be painted.
