It

doesn't sound like the problem is with the airbrush. What you're getting is little chunks of dried paint from a previ-

ous painting session. They're loosened from the inside of the needle housing or the paint siphon by fresh paint. Simply

blowing thinner through the airbrush after every color sometimes isnt enough to thoroughly clean it. IfI'm spraying one color after another in a single sitting, I'11 take the airbrush apart and clean it after every three colors.

No, because CO2 in a cylinder is liquefied and anhydrous (without water). The gas cools as you release it from the cylinder, but because there is no water or water vapor in the cylinder, no droplets will form in your airbrush line.

Assuming your problem is getting the outer wheel rims to stick to the inner wheel rims, first make sure you scrape away the chrome plating on the surfaces to be glued. Plastic cements cannot penetrate this plating and a bond is never achieved.

Soak the picces in hot water, then gen-

First, glue the forward fuselage and 1et it set for at least a day. Make sure it is a strong joint (you may want to reinforce it with a bead of gapfilling super glue if you can gct to the inside of the fuselage). Repeat the procedure for the tail section, forcing the halves together. Wrap rubber bands, pipe cleaners, or strong tape around the rear fuselage after the glue has been applied and let it set for 24 hours. This can work for warped wings as

sandpaper is available in many brands and grits and is usually dark gray. Use 220-, 320-,400- and 600- grit papers for mod-

eling. The higher the number, the finer the grit. The advantage of wet sanding is that water keeps the grit from clogging. With cleaner grit, the sandpaper works faster. Sand at a utility sink, occasionally passing the sandpaper through a stream ofwater from the faucet.

Tim Malone

Actually, your first method is a little overkill. Apply thc first decal using only as much solvent as is necessary to get the decals to snuggle down over the detail. Wait for the decal to dry, then lay on the second layer. (If too much solvent is used, you risk stretching the decal, making it nearly impossible to line up the second layer in register - you would have to stretch the second decal in exactly the same places to get perfect rcgister.)

A wash is a highly diiuted paint used

to add a visual illusion of

depth. For

instance, thinned black paint brushed onto an aircraft wing will settle in panel lines and hinge lines. Washes can be brushed on figures to add natural shadowlng.

Use a paint and thinner that wont harm underlying coats ofpaint. Ifyou use lacquer color coats, you can safely use an enamel wash over them. Don't use lac-

quer over enamels, though, because lacquers will eat through enamels quickly. IJse an acrylic r.vash ovcr cnamels.

Gloss-white coveroge I'm painting with Tamiya gloss white (X-2) but I'm having trouble getting it to cover. It leaves brush marks and it wont stick in some areas no matter how many coats I apply. I tried washing the model in warm, soapy water, but it didnt help.

- MarA Schicker This paint seems particularly sensitive oi1 on thc plastic surface. Tiy wiping mineral spirits or rubber cement thinner

to

over the trouble spots after washing them

with

soapy water. These solvents will

loosen oils without affecting the plastic.

My favorite white paint is Floquil's Reefer White, but this should be airbrushed. For hand brushing, I like Polly Scale White. Both of these colors dry flat but will accept a clear gloss overcoat.

Pqint before or ofter

I wonder why the models I see in FSM are built before being painted. I dont see how you can paint after the thing is built.

A

combination

Devine

of painting interior

detail before assembly and exterior finishes after assembly is the best way. Painting after assembly allows you to cover filled seams and gaps. For an airplane, build and paint the interior (cockpit) first, then paint the

interior wa1ls of the fuselage

halves.

\,Vhen the paint is dry glue the cockpit in place and glue the fuselage together.

Fill

seams

with super glue, add a touch

accelerator to harden the glue, then sand it smooth. Then glue on the wings and stabilizers, filling seams along the way if needed. Now you're ready to paint the outside of the model. You can siick a brass tube up the tailpipe or into a hoie for a propeller to hold the model while you paint. Find a way to mount the brass tubc (with the model on it) to keep from touching the paint before it dries.

colors as bcst you can. To simulate the field-applied camouflage, try thinning the paint and applying it with a brush or

an eye-shadow applicator - a small, round, spongc-covered tool that, with practice, can produce the rough handapplied paint look you want. The model wouldnt need to be in a diorama if properly labeled, which is not a bad idea - not everyone who sees your

work is going to know what it is. It wouldn't hurt to let your audience know the paint job is supposed to look the way it does. The qualiry of your construction and underpainting will show that you aren't ham-fisted.

bristles, but they're expensive. \ No brush will keep forever, but a good brush will keep its point with proper cale. Clean it immediately after every use with a thinner that will dissolve the paint. Dip the brush in the thinner, but never let the bristles rest on the bottom ofthe container; that bends them. Pull the brush along a clean rag. Dont scrub it or jam it into the rag; that bends and even breaks bristles. You may need to dip and wipe several times before the brush comes clean. To restore the brush's point, put a drop of saliva on your fingertips and draw the brush through. This will hold the bristies in place. Put a plastic-tube cap on the brush and store it upright.

Testor Glosscote and Dullcote are lacquers which, properly applied, can go over enamels and acrylics with no problem. However, dont hand brush them. The application will be too thick and the wet lacquer may eat through the underlying paint. You must be careful with spray cans as well.

Make sure the underlying paint

is

completely dry - wait a couple of days for flat enamels and acrylics, a week for gloss paints. Spray light coats of clear and wait a halfhour before applying another coat. Ifyou build up the overcoat too fast it can soften and ruin the colors below. Airbrush these clear coats from the bottle with about25 percent lacquer thinner. Dust on several light coats and never allow the overcoat to puddle.

Sproy mqtters I'm worried about using Testor clear coats over enamels and water-based acrylics. Can I brush the bottled versions
