Paint prep

[Marshall Nay]

I've found a product that the auto industry uses to improve the bond of paint to the kind of plastic we use. It's called an "adhesion promoter".
I'll try it and report back...

That's a very good question Ironsides. I must go and experiment with my daughters toy animals to see how tough their paint job is but I don't think it is particularly deep paint coat..

That is a good point, the scleich animals. On this forum someone asks the question on how to repaint and make it permanent;

and I think the answer refers to these types of Acrylics;

and the sealant, maybe this;

Hi Marshall Nay as far as im aware there is no actual wax in T-Cut as it would as you say defeat the object... which is to prepare a surface for re-painting... a courser version is usually called something like "Car Body finishing paste" a fine abrassive paste.... use with caution on your car...
The adhesion promoter sounds interesting..
I wonder what companys like Schleich use on there figures(90mm) its a sort of hard rubbery plastic and paint finish seems permanent, does'nt flake, crack or scape off....and they all look hand painted...

Cheers

I read later that T-Cut is designed for the auto body, but I'm finding that the auto industry offers all sorts of substances for painting semi-flexible plastic. Dupont, 3M, Sherwin Williams (and others) manufacture a dizzying array of products. My local shop (Kragen's) sell the Sherwin Williams line: Dupli-Color http://www.duplicolor.com/products/adhesion.html (then go to their products page). It probably means a visit to "the school of hard knocks", and I don't want to spend anymore than I have to, so it will take some time. But it looks promising. If anyone feels inspired to join the hunt, please post any successes.

Here's an alternative to the adhesion promoter: Flexible Primer http://www.duplicolor.com/products/pro_primers.html (scan half way down)
We really have two discussions: preparing the surface and priming. I'm going to use the powdered pumice to prep because it's cheap, easy, and I have it. Then I'm going try the adhesion promoter. If someone wants to try a flexible primer, another brand of adhesion promoter, or another prep method please post results. The more the merrier.
