Vallejo: What gives?

Tools, Techniques, and Reference Materials Painting and airbrushing
1

I recently bought some Vallejo RLM 05 as nobody else seems to make it.

I mixed the paint as per comments that I’ve read here on the forum, using water instead of my usual Tamiya thinner.

I sprayed my model, it all looked OK.

However I came back to it next day, and a couple of black marks had appeared on one wing. No big deal, I simply oversprayed and left it.

Next day same thing.[banghead]

So I thought I’d rub the offending area down to bare plastic again.

That’s when the trouble began, as the paint started tp peel off in strips at the slightest touch!!!

Anyone got any ideas what I did wrong?

Thanks

Not sure what caused the spotting but I find the best results are obtained when you apply the distilled water thinned Vallejo OVER a suitable lacquer or enamel primer. I use Tamiya Primer which provides a great base for the Vallejo acrylics. This prevents them coming away from the bare plastic as you described.

My 1:72 Airfix Gnat brushpainted with Vallejo over brushpainted Humbrol Lt Grey enamel. The gloss was obtained using Future.

Dubix,you’d have thought!

I’ve become used to Gunze, where a primer is not really required.

I’ll try undercoating it first with Gunze flat white, and see how that goes.

Madmike, I love the Gnat, I remember that kit from when I was a kid.

As for the Rotordyne, stunning looking build, of a little known prototype.

Thanks for your help guys.

Bro ya gotta sand the plastic with a very fine grade or Those vallejo’s wont stick. A primer is good but not neccessary if ya sand the model first. Don’t forget to wash the model before painting. I have switched to Vallejo’s and love em. DO you notice how little you need to thin them… I think its great. Have you seen the model air line yet?? Made for the airbrush. I havent tried them but my LHS stocks the whole line.

Ooo forgot to add… you didnt mix the paint enough. Thats why you have black there. Shake those Vallejo’s HARD for a while. That’s how I get my finishes with them.

Vallejo OD done as I decribed above…


Hope this helps ya out Karl

Karl, as Jeff said you have to shake the paints well before use.

When thinning them use only distilled water, as normal water from the tap can contain impurities that can effect the paint.

Jeff, I sanded the entire model with 1000 grade wet & dry, as I had to remove a pebbly finish from the surface prior to painting, so the surface should have been properly keyed.

Maybe I didn’t stir it enough before applying, that would explain the black marks.

I saw the AB ready paints on Vallajo’s website, but I don’t think that they are available over here. Having said that, even if they were, you know how I feel about my Gunze!

I’ll try a coat of Gunze white before I put on the Vallejo next time.

Thanks for the feedback guys.

I use Citadel Miniatures Chaos White spray cans for priming.
Then I spray Vallejo using a 2:1 paint :water ratio - this gives me the best results.
My LHS recently started stocking Vallejo Model Air pre thinned paint , but I havn’t tried it yet.
