How do I use this?!?!?

[klutz_100]

Can't believe I'm asking this bit....hgow do I use this Mr. Metal Primer. Instructions for use are in Japanese and covered with a Hungarian label



Do I thin it? airbrush it? Brush it on? Does it eat plastic? Does it replace eg tamiya proimer spray or do I use that after?

Really appreciate your help

Airbrush is best but you can always try using a brush to apply it. I think it is safe on plastics.

Thats for diecasts mainly. I believe it has an etching agent in it to etch the zinc in cast white metal.

Actually it is for what it says. It is for priming metal parts. This includes photo etched parts in brass, stainless and nickel. White metal such as in many 1/43 kits and parts like Tamiya gas tanks provided in the special addition FW24 kit. For die cast cars you would want to use automotive primer. For metals that are smooth as described above thi Mr Metal primer or Tamiya clear primer are better. The do etch into the metal but also protect it from tarnish if it is to be left in a natural finish and it does not build up thick like regular primers.

You definitely want to use a metal etching primer on diecast models as well. Automotive primers chip very easily from the zinc-rich material, usually Zamak which is a common die casting alloy that diecast models are cast in. You can use the Mr. Metal Primer on diecast, or you can find spray cans of it at auto parts stores, Duplicolor makes some as do other brands. Regular auto primers don't have the chemicals that bond to the metal. You can certainly use auto primer, but it's best to use it on top of the etching primer which should go down before any other paint or putty.

From my experience, it won't damage plastic (sometimes I use this as primer for my model cars if I'm too lazy to go and get plastic primer). It is best applied using airbrush and thinned with Gunze Thinner.

The Mr Metal Primer is used to coat, what else, metals of course. It is used for priming etch parts and other metals. The downside is that it is clear, so you have to make sure that you have applied it evenly throughout the surface. It also comes in a spraycan.

Thanks gents - much appreciated!

Interesting to note David's comment that it can be used a sealer on metals - just what I need on my 2CV dampers
