Got the heater unit fitted up .... holes in the firewall etc. Fits in very nicely, though I've now got it out again while I sort out insulating the firewall, at least the bit behind the heater unit.
I hit the firewall and toe board areas with my angle grinder and wire brush.....should have seen the stuff fly....dirt everywhere, lol.
All cleaned up with wax and grease remover then got stuck into a few coats of my home made insulating paint.
The paint is a mix of epoxy anti-rust paint and micro-balloons (aka micro-spheres).....50/50 by volume. I turned 500ml of paint into a litre of this stuff, then coated the firewall until it was all used up.
The micro-balloons are tiny glass spheres that are hollow...suspend them in a paint base like this and it forms a nice insulating layer. There is a commercial product called Lizard Skin that uses this method, but they use a latex based paint and are way more expensive...I'm not even sure you can buy it here in Australia.
Anyway....I'll get some Dynamat Xtreme sheets to go over the paint and add a firewall pad over that of Dynapad....which is a multi layer noise and heat barrier.
