Homebrew PCBs

I have been following post with interest, even though I only use the Photo expose and etch method. (I have had consistent results with 2 layer boards)As some members seem to be prepared to experiment with various solvents to achieve good  and repeatable results, how about trying Brake Fluid?As this substance seems to dissolve a wide variety of plastics, natural and synthetic Rubber, Car paints. (Including factory finishes! This method was used in the past, some "muppets" had daubed a bottle of brake fluid all over my buddy's car with really nasty results)

On a related topic using the same post heading; -Has anyone used, or tried using a low power Extreme Ultra-violet (UAV) LASER (I cannot remember if it's 40 or 400nM) to expose the photo-resist clad board?. At the time of attracting my attention these LASERS were on sale at 45.00GBP!!!!
My set-up would involve a standard PCB CNC table with a "Qwick-Connect" adapter to allow rapid change of the Z-axis between Drill and LASER mounts.I have asked about this topic in the past and received no response, but this was during a period of my account being hacked
