Paints?

[Eddy Matthews]

Just to save me having to test it, does anyone know off hand wether Humbrol enamel paints will go over the top of Halfords acrylics? Or will they react with one another?

Can't say, I've never tried, but I have found that a good way to get a weathered, cracked and peeling effect (if you ever wanted to build a model of a semi derelict, in need of restoration old wooden boat) is to use Revell satin white then Humbrol matt white over it. I tried a test area on a piece of ply - good thing I didn't use it on the Freshwater... :shock:

Having been in the painting trade, workwise, it is taboo to mix water based paints with oil based. Albeit one can paint over almost every surface that they wish, the time factor will tell all. Oil based paints never really dry out as such, and remains in that state for many years. Putting a non oil  based paint over, will result in a possible cracking of the surface, it cannot give at all, the oil base can.
Putting oil over water based may work, but not the other way. It could take some time to notice this effect, the choice is yours. Oil based paints can be remove by most normal means, not so water based.
I do not make models, but work on the real thing, a full-blown paddle steamer ‘Medway Queen’ fighting for survival.
I do advise on the paints as relevant to this project, bearing in mind the cost for the job in mind, and necessity of the life of the relevant job.

Thanks guys,

So hopefully with the water based acrylic as the base coat I *should* be okay putting an oil based enamel over the top?

You've probably opened a can of worms there Len - I can see everyone grabbing you with any questions on paint from now on! :-)
