A lot of people online seem to really hate this stuff. Others report that it works fine. I’m somewhere in between, so just to confuse things, here is my experience with using it, but no real conclusions.
Stuff I like:
Easy to spray. Put it in a large-nozzle airbrush, crank it up to 20psi, and hose it on. Thinning (with Vallejo Airbrush Thinner) is not needed, but you can dilute it down a bit if you like.
Water cleanup (mostly.) A bit of thinner makes it clean up easier.
Dries to a very smooth surface.
Available in lots of colors. (Skeleton Bone, Ultramarine, 4BO Green, White, etc.)
Can be mixed with Vallejo Model Air/Model Color and presumably other acrylics.
Can be brushed on with good results.
Dries pretty rapidly.
Can be lightly dry-sanded to remove runs and goobers.
Stuff I don’t like:
Dries on the airbrush needle tip something awful. Adding flow improver doesn’t seem to help much.
Tends to pool at inside corners, and pull away from outside corners.
Needs a fairly high pressure and large nozzle to spray, which could be an issue if you’re trying to paint detail. (But then, why are you using a primer for that anyway?)
Doesn’t adhere very well to bare plastic, even after pre-washing. It sticks great to Tamiya spray can primer, but if it’s already primed. . .
Doesn’t like being wet-sanded. Tends to come off in sheets.
Hard to clean if left to dry on a paintbrush.
None, as I stated up top. I’ve been using this most recently because it was the right color. I won’t go so far as to throw it out, and for small spot-fills using a brush it’s pretty good. It’s thinner than the grey Tamiya Liquid Surface Primer in the square bottle, and sometimes that’s the consistency you need. I just haven’t been able to get consistent results using it as a primer for plastic.
It’s possible that the formula may have been updated since I bought this bottle several years ago. And as always, your results may differ from mine.
Here’s one of the reasons I haven’t done anything much lately.
Well, also I’ve been putting baseboards in a closet, but this is more interesting.
Dark wood is bocote, the light is cherry. Spray lacquer finish. The dinosaur is about six inches long, to give you an idea of size. The others are a bit smaller, but perspective and junk.
Originally I’d planned on doing the joints with dovetails, but it didn’t turn out well. The main box and the drawer sides are all rabbetted, and the box on top is simply butt-joined. Some of the edges don’t line up as well as I’d like, but I oriented things so that the ugliest bits are around the back. Mostly.
The divider strips on top don’t define closed areas so that I can slide things out if I can’t pick them up. Sometimes it’s hard to grab little paintbrushes or tools if they’re right up against an edge. The strips are rounded or beveled (depending on what I felt like at the time) as well.
Initial design was done in Trimble (formerly Google) Sketchup. I didn’t do a very good job of it, but it was enough to go by. It’s not hard to use, but I didn’t feel like investing time to learn it thoroughly since I don’t plan on using it a lot.
Yes, I’ve really been working on the tool organizer. I just don’t have any photos. (It comes down to the old ‘Do or Tell’ decision.) It doesn’t look so hot, so you aren’t missing anything. The top is cupped, and the joints don’t meet very well so there are gaps. But I had fun with the router, so it’s not a total loss. It will be functional but not much more.
