Rainbow effect/oil sheen.

[sharowjohn]

Has anyone out there worked out a way of producing the rainbow like oil sheen seen when small amounts of oil are spilt on a wet surface I have been trying to figure a way for a couple of weeks now, all to no avail.


Cheers sharow john.

Is it on a dio John ? If its an oil spill or suchlike maybe a clear pearlescent nail varnish painted over the dark painted puddle will give the effect . Hope this gives you something to go on , cheers tony

Hi,


I should have been a bit more specific to start with; yes it is a diorama underway Skoda 30.5cm siege howitzer on a wet day. I have found something which produces an oily sheen of all things release oil! just a tiny drop in water I think it might look a bit over scale but am working on it that and release oil proofing the model.Still open to suggestions/advice will report back on progress as and when.


Cheers sharow John.

The only way I can think of to get them to scale is to photograph some real ones scale them down and print them on clear decal film....

Hi, do you mean something like this?

IF YES, you can try this. Just dip into it and leave it until it dry/cure.

While since I have been online so update tried photographing a couple of real sheens but I don't think my photography skills are quite what they should be, but floor polish looks worth a try .

I'm interested in how it turns out I need to create some oily water.

I would like to add to this, after something I noticed tonight with my own model.


I was giving a dirt wash to my car (1/24) using a thinned down Vallejo Air, applied with a brush. Now my model is plainted with car paint, and has an aerosol glossy clear coat on top.


I noticed that my previous wash had dried in a fashion of leaving a circular tide mark and fading to nothing towards the centre.


My suggestion would be perhaps to put down a little clear coat. Mix up a paint of suitable colour and just gently put a nice blob down. Hopefully held spherical by surface tension and allow to dry. Another coat of clear, a different colour in a smaller blob and procede until the middle?


This is just a working theory of course but it makes sense in my mind
