Would appreciate guidance on an issue of paint compatibility...
I'm refurbishing old Crittall windows (galvanised steel frames). I intend to paint the frames with Rustins 'quick dry' metal paint, white:
https://www.rustins.ltd/rustins/our-products/speciality-paints/quick-dry-metal-paint-black
The Rustin's paint is water-based and can be applied directly to the bare galvanised metal, according to the data sheet. I also have some Johnstone's smooth metal paint in a creamy colour:
https://www.thepaintshed.com/johnstones-smooth-metal-tinted-colours-cp35192
The Johnstone's paint is solvent based and doesn't appear to be suitable for painting directly onto a galvanised surface.
Question is: Can I use the Rustin's paint for the first coat then, when thoroughly dry, apply a final coat (or maybe two) of the Johnstone's metal paint? Or will there be a compatibility problem between a water-based paint and a solvent-based paint? I can roughen the surface of the Rustin's paint to provide a key, if that helps.
