Just use the Acrylic sprays. ?Silicon conformal is too expensive for non pro stuff aka this is for avionics of naval electronics. ?
Cap any sockets snd plugs before use. Indeed I wouldn¡¯t spray ICs that are socketed like CPU/Pic42s/EPROM ETC. ?These need good contact surfaces. You don¡¯t need a thick coating. ?Indeed usually spray into cap and brush it on as necessary.?
Clean up with acetone?
cheers, well done?
