I use Alclad exclusively. Tried almost all the metalizers, for me, nothing comes close to Alclad.

As for any metallic paints, the key to a flawless metallic finish is a good surface preparation. Super smooth is the only way to go.

Many modellers are having issues with Alclad, I've never had any problems. Give it a try.
Always use a primer, Mr. Surfacer 1000 thinned with Mr. Color leveling thinner is my weapon of choice. Couple of thin layers are more than enough.

Apray Alclad at low PSI (less than 1 bar) from a close range (4 cm). Don't try to wetcoat the model with it. Build it up in layers.
High Shine tones of Alclad (Chrome, Polished Aluminium etc), require gloss black base. Otherwise it won't adhere well to surface and it can't be masked. I've found that the best gloss black is Mr. Color GX 02 - Black Gloss. Super shiny, dries in a matter of minutes. Can be polished.

There is no need to seal the finish, you can mask over Alclad with no problems.
The range of different tones is huge, but you can also mix a drop MM Metalizer to achieve tonal difference.
Decals can be laid directly on to Alclad. But just to be sure, i brush a coat of Future where the decal is to be placed. Use decal solution of your chioce. I use Microscale products. Be aware that some decal solutions react with metal finishes. Do the test sample on some spare plastic to aviod unpleasant surprises.

Final coat. I guess Alclad aqua range is great, but I use Mr.color varnishes. They are tuff and durable and don't yellow over time.

But as Mr.Craig said, this is only one modeler’s opinion...

Hope that helps.

I will say I can mask most of the metalizer colors successfully with 3M blue painters tape that's been stuck to something and lifted to get rid of some tack. Aluminum Plate buffing ain't having none of that though, so I spray it last. A question about the Future. I've never used it ever. I do want to know if it would create the effect I'm after which is this. On some photos of natural metal EE Lightnings, there is a glow and depth to the aluminum. I don't know if it's from residue left over from polishing compound or what, but would Future replicate that, and how would I apply it?

Anyone here have any advice experience using the SNJ products?
