Hey Omar,
I posted the same question on Hyperscale about a week ago...I just finished a 1/32 109G-6 and was concerned. I was told to wait 24 hours after the Future was sprayed just to be safe.
I did, and everything was alright. However, make sure you don't allow the Sol to puddle up, because I did have an instance where it stained the paint and Future. It ended up looking like a water spot, but I sprayed it over and everything was fine.
