    Default Coolant/Oil proof paint?

    Hi all,

    I'm 3/4 through knocking up a new bench for my lathe, to which I will be adding and enclosure and flood coolant setup.

    The construction is of pine and ply but I will be fibreglassing the top ply top to waterproof it and to make it a bit tougher.

    Once I've finished I want to give the whole lot a lick of paint. Are there any paints I should not use (will react to coolant or oil)?

    I've always liked Hammerite - for its out of the can 'industrial' look, its toughness, and the fact that it is really good at hiding crappy surface finishes (not that I ever have timber with a crappy surface finish, that is...cough...cough...cough...) rather than highlighting them.

    If you are keen on making the top coolant/impact resistant, use a few coats of epoxy resin rather than polyester - it sticks a lot better to wood and its more water/solvent proof (see the boating threads on how to apply).

    Thanks for that. I had heard of Hammerite, but I didn't realise that it could be used on wood. Any ideas on who stocks it?

    The big green shed has it - or the killrust equivalent. I think the 3D Paint stores may stock the genuine hammerite, but the one I got from bunnies seemed pretty good.

    Well I finished off the base. I fiberglassed the top and used the hammer finish paint from bunnings. I still need to work out how I want to rig up the top enclosure. I might just put some sort of screen on a hinge at the front to stop stuff flying everywhere.

    Phone photos so they are poor quality

    When I was restoring my power hacksaw I was looking for a coolant proof paint .I used killrust epoxy paint to paint the machine and was still worried that the coolant would eventually lift the paint in the areas where the coolant was present for long periods.
    I spoke to a fellow who builds RC model aircraft ,and he told me to coat the areas with exterior marine Estapol ,it will protect the paint from the oil and prevent flaking and peeling .The model aircraft builders use it to protect thier painted finishes from the model aircraft fuel.
    Well I did what he said and so far so good , no paint degradation.
