" "dry spray silicon" will most likely ruin future paint jobs."
Do not use silicone "On [near] painted surfaces... the paint sucks up the silicone and makes paint prep ever more onerous than it normally is (if that's possible)! Paint will not stick to silicone, so always minimize overspray when using silicone near painted areas (door hinges, locks, etc.)."
Many years ago, I threw away all silicone-containing spray/lubricants.
If you use those sprays in a spray-painting room/booth, good luck decontaminating.
