Hande,
Why bother?
A few times on the lake and the props will look perfect.
They will corrode naturally.
Real ones get a jet wash at each docking and if they
are lucky a polish with a wire brush.

I guess it's true, Ned.


However, this exercise serves as a learning lesson, too.
Lessons learned:
- there is no universal truth about the matter (I was hoping for one)
- some techniques can be outright wrong - be aware and research for advice
- some fundamentals have to be learned, no matter what
- most of the ideas about painting props are in vain, as the paint will probably fall off
- somehow, I must learn to paint in thin coats - it's diffcult for me {:-{


plus I had the possibility to postpone the painting of the actual build.
It's like the white paper syndrome of a writer :embarrassed:

I will report on my experiment to the (bitter?) end, for the enjoyment (?) of those that are interested.


I got the U-Pol Acid#8 (Thanks again E2V!) etch primer.
Sanded.
Degreased.


Primed the props and their hubs with the spray can.
Primed portholes and bollards and drop stoppers by brush.


The portholes were glued on already, so I couldn't sand them (or wouldn't, rather).
The drop stoppers above the doors are of copper. They were sanded, but still the primer didn't adhere well. Maybe, when the etching kicks in it does.


I learned from the source that Stan posted (thanks, Stan!) that etching will happen after the primer has dried. Although the instructions of the product that I use say that curing will take place in less than 20 minutes, i found it takes longer than that. I may have had unnecessarily thick coats (according to instructions, 2 coats would be ok). But indeed, when dried, the primer has stuck pretty well.


The primer seems to stick  :} O0

I don't know if you have underfloor heating in your wet room, but I find it a great place to dry painted parts


Just make sure no one takes a shower

I have an always-on sauna - mildly warm all the time (I open the kiuas, when we actually go to sauna). That's good, too  :-)) {-) O0

How very interesting  O0
The patina techniques take the discussion to a new direction.
Patina doesn't fall off, for sure. It may change?
Are they widely used among model builders ?

This is where I stop painting the props and the rudders until I get to sailing.
The second picture should show the bronzy shade that I created by mixing bronze metal and boltgun metal together.
The anchors got the same colour, except for the varnish being semi-matt, instead of glossy.


We'll see, if the paint holds ...

That is a lovely colour.... I'm guessing you're using Games Workshop acrylics judging by the names

It's all Vallejo. I figure as long as I stick to one brand, it's all compatible.

Correction: it's Vallejo "Gunmetal".
"Boltgun metal" is a Warhammer paint, of course. Very much the same colour.
