Applying epoxy primer to small steel fittings
Posted: Sun Aug 03, 2014 8:37 pm
The four wing panels for my project have been successfully trial assembled, with all the many small metal fittings ready to be bolted in place. Some need to be fitted before gluing up the assembled panels. A few are visible outside the finished wing panels and so need a suitable finish paint.
The fittings have all been etch primed(two part) and epoxy primed/undercoated. Some have been marred during trial fittings and need patching with epoxy primer. I do not wish to tangle with spraying epoxy again; a filthy business and lethally unhealthy, as well.
Therefore, I need to do this with a decent brush, but do not wish to end up with a thick and untidy finish, after going to a lot of trouble spraying them the first time around to achieve a thin coat and a good finish.
I was hoping to leave the fittings in their cream epoxy undercoated state, where they live inside the wing panels and only overcoat those that are visible outside the wings. It has now been suggested that they should all really be given a decent finish paint coat.
I can't seem to find much information about how best to approach applying epoxy paint by brush; I already know it is very difficult to end up with an even thin smooth coat, from earlier experiences.
Can anyone suggest how to do this with the minimum fuss and recommend a good epoxy primer/undercoat that is available in less than industrial quantities? (I have used Hempel (marine) epoxy paint so far( a cream finish). The two part etch primer was from LAS & produced a lovely even finish.
So far, I haven't found any two part epoxy "top coat" paints that are available in a range of colours. Is there any alternative to the Randolph range from LAS/ A/Spruce? Does it have to be epoxy? I don't need gallons of the stuff, having already thrown away vast amounts of part used, time expired tins over the years.
