I noticed they had a "pre-primer" whats the benfit of that?

mm10 gesso
mm27 low viscosity gesso
mm26 transparent gesso
mm25 black gesso

dug around and found a few posts on wargamerau..
someone got a reply derivan from derivan yesterday about something similar in the "derivan minis paint range" topic:

FYI – I've had a response from Derivan this morning:

Hi,

I have an enquiry about specific products in your Derivan MiNiS range; White Primer, Black Primer and Pre-Primer.

Q: Pre-primer. What is it and what would it be used for in relation to miniature painting please?
A: this is used to give better adhesion between "plastic" molds and the paint- we had several requests for something to help the paint stick to the plastic miniatures which were predominately PP or PE plastic, this chemical promotes chemical adhesion. (for instance on swords and rifles which were very flexible this will add adhesion and resist cracking – to a degree…..)

Q: White and Black Primer. Are they suitable for airbrush application on to a miniature?
A: yes they are however you will need to reduce them a little with water- how much water will depend on the type of airbrush you are using.

Q: Would they need thinning and if so what thinner would you advise that will not then melt a plastic miniature? Do you know what the recommended psi would be for application?
A: As above-thin with water only as the paints are all water based- they will not melt the plastic, pressure and type of equipment is purely up to your discretion.

I hadnt heard from derivan (network problems they've just moved) so I rang them.. spoke to a David Mc Lachlan in their QA area..

the minis range white and black primer is the same product that gets sold as matisse medium gesso and black gesso.

Either of these can be blended with another colour although he said the transparent gesso on figures would be ok, thinned a bit unless you chose the low viscosity gesso which would work better with miniatures.

the sales rep ws out but he told me the paint was availble in australia from warpuppy.

Thank you sir, for that for a moment there i thought we may have found a Rustolem equivalent in Aus.

Cheers.

actually I think you may..
As I dotn paint plasrics I neglected to mention that David from Derivan mentioned that the Derivan guy confirmed to me that the pre-primer was specifically meant for plastics

Most of the miniatures here are plastic and I used the pre-primer.
