I am now done with stripping and It is time to settle on a paint system and a colour scheme.
Colour is easy I have decided to go for the original dark machinery grey with a mid yellow on the under pinnings and I will need some red for the lettering which I will use for a couple of other highlights. I have sample of the 3 colours The grey is inside the cabinet the yellow on the bottom of the steady and the red on the name plate. I want to avoid really toxic paint products which will place some limits on what I can use. The internet is full of information on how to paint old machines and I looked at a heap of it and this is what I have decided to do.
Like many machines of its age it was filled and painted and I have a couple of options here but have decided to lay down a coat of epoxy primer and filling over this. The epoxy seals the surface and provides a good bond to the base metal. The biggest drawback is that it is a 2 pack paint so once it is mixed it needs to be used before it goes hard. I intend to deal with this by having extra parts ready to coat so as to reduce waste. I will brush this on it some areas as I will not be able to get into them to spray them. then spray the rest using a 2.5 mm nozzle. As mentioned above if I decide that I need to add a spot of filler I can put it over the primer for the first few days after that I am told that I will need to sand it back.
The second coat will be a high solids primer. This will be applied as above then sanded to remove any rough spots The high solid just means that it will be a little bit thicker coating. I need this coat because the enamel will not bond to the epoxy that I have chosen. Again I am planning to use the large nozzle for this.
Then to top this off a couple of coats of slow dry enamel I may drop to a 1.8 mm nozzle for this and even a 1.4 for small parts.
This sounds pretty easy but there is still a lot of cleaning and prepping to do some areas are quite hard to get at and progress is pretty slow. Nozzle sizes are one of the things that I have learned about. I had though just buy a little gun as you have little parts but the touch up guns tend to have smaller nozzles and this means that they require the paint to be thinner and that the thickness of the coat will be less, also it means that it is hard to get the film to a thickness where it goes smooth and forms a skin over the whole job I managed to find a kit with 3 sizes 1.4, 1.8, and 2.5mm as the large nozzles put paint on faster the will not be so good on small parts because areas that get an extra coat will be prone to runs and it will be hard to control.
I found the Eastwood website to be a wealth of information https://garage.eastwood.com some great videos and how to articles. They are car people but close enough.
