if I was to use tamiya paints for preshading and then applied enamels over them would it cause a reaction between both paints?

Hi,

I don't think it would cause any reaction, I've been using enamels over acrylics and acrylics over enamels for years and I've never had any problems.....just let your pre-shading or undercoat dry thoroughly before putting any other paint on top is the only advice I would give

Hiya Mikeli,

I did it with the IV that I'm working on and had no problems at all - choclate brown tamiya preshading and then over that with humbrol dark yellow.

As Simon said, better to be safe than sorry and let it dry for day or two.

Cheers,

Cokes.

This does not present problems. I've been painting my models with Tamiya for years now, but always use the Revell clear varnish before I begin washing & weathering.
Never had any problems with the acrylic/enamel combination....

As long as the base coat is cured there should be no problems. I suspect that some of the troubles that you do hear about result from people trying to completely paint a model in a space of hours. This means that fresh paint is being applied over uncured base coats and can result in lifting of the base and crazing.

I dont expect people to be as slow as me, - four weeks between enamel base coating Chieftain and applying the first acrylic weathering wash, - but certainly the longer paint is left the better.

Enamels dry from the outside, which may seem very obvious, but it means that the skin that feels dry on the outside is actually covering the uncured body of paint. On full size enamel paint jobs a 'thick edge' that has formed can be opened up by applying finger nail or knife blade to reveal soft paint weeks after the paint was applied.

Same here. I applied a base coat of Tamiya Buff (enamel) in my M113 kit. Then after drying, I applied Tamiya Olive Drab (acrylic) over it. There is no adverse effect.

You won't harm your model. I never had problems spraying enamels over acryls or vice versa. The only one thing is to be sure that the paint has throughly dried...
