Is it necesary to give a primer coat when you will use a metalizer paint ? I read somewhere that it´s better no to use it because the plastic has a better (smooth) surface than the paint. Is this true ? What is the reason of the primer in this case ?
I´m building a F 84G and I will use Model Master Metalizers. I will appreciate your advice
Do not use a primer for MM Metalizers, for the exact reason you not. Primer has a rough surface to allow later coats better adhession. Metalizer pprovides an extremely thin coat which will show the primer's texture, spoling hte effect of the metal finish. In fact, it would be best to polish the plastic with ultra fine polishing pads for the best effect. Further, Metalizer is a relatively
hot laquer based paint and as such will bite quite well into the plastic. It's this feature that precludes its being brushed on in any but the smallest areas.
What holdfast is talking about is automotive paint, not metalizer. That's a whole different type of paint, hence the need for primer, since auto paint is even [i] hotter [/] than Metalizer and could damage styrene, even if sprayed on.
