A sunburst is one of the most rewarding finishes you can spray at home, and it is more forgiving than it looks once you understand what you are actually building. This tutorial walks through the burst itself: the gradient from a bright center to a dark edge, the spray order, and the mistakes that trip up most first-timers. For the underlying surface prep and clear-coat basics, follow the painting tutorial and use this as the burst-specific companion.
Applies to: any solid-body kit you plan to finish in a translucent sunburst, especially kits with a maple or veneer top. This is not for opaque solid-color paint jobs, where the wood is meant to be hidden.
What makes a burst
A sunburst is a smooth gradient of color that runs from a light center out to a dark edge, with no hard line anywhere in between. You are not painting shapes. You are building up thin, see-through layers of tinted lacquer (called toner) so the wood still glows through in the middle and gradually fades into shadow at the rim.
Three ideas do all the work:
- Translucent, not opaque. Toner lacquer is tinted but see-through. Light passes let the grain show; heavy passes darken it. You control the whole effect with how much you build up, not with the color of a single coat.
- Light center, dark edge. The middle of the top stays brightest because it gets the least dark color. The edge gets the most.
- Feathering. Every color transition has to fade, not stop. A feathered edge is simply spray that thins out gradually because you are holding the can farther away and keeping it moving.
Choosing your colors: 2-tone vs 3-tone
2-tone burst. Two colors: a light center and one darker edge. On a maple top that is usually an amber or honey center fading straight into a dark edge. It is the easiest to control because there is only one transition to blend.
3-tone burst. Three colors: a bright center, a warm middle band, and a dark edge. The classic version is an amber center, a tobacco (brown) middle, and a near-black edge. It looks richer, but you have two transitions to keep smooth instead of one.
This tutorial builds the full 3-tone version. For a 2-tone, skip the middle tobacco band and fade the amber center straight into the dark edge.
What you need
- Sandpaper and a sanding block
- Painters masking tape, plus fine masking tape for protecting any binding
- Woodgrain filler and a scraper (a damp rag also works)
- Acetone for cleaning, if available
- Black stain to pop the grain
- Aerosol toner lacquer in amber and tobacco (plan on 3 to 4 cans)
- Aerosol clear lacquer (plan on 3 to 4 cans)
- Wet-and-dry sandpaper in a range of grits, plus a buffing or polishing cloth (see the painting tutorial for the full rubbing-out schedule)
- A large piece of cardboard for the spray mask
Step 1: Prep and pop the grain
Get the top flat and clean first. Sand back with a sanding block, working with the grain, until the surface is completely smooth, then remove all dust and wipe the body down with acetone if you have it. Work woodgrain filler into the top, first with the grain and then against it, using a scraper or a damp rag. The painting tutorial covers this foundation in full, so keep it light here but do not skip it, because a burst shows every flaw underneath.
To make a figured maple top come alive, rub black stain into the face with a lint-free cloth, get an even coat, then wait up to 30 minutes and gently sand it back. The stain stays down in the grain lines and lifts off the flat surface, so the figure pops.
Watch the veneer: on a veneer maple top the wood is very thin, often 1 mm or less near the edges, and once you sand through it there is no getting it back.
Finish the prep with 2 to 3 coats of sealer so the toner lays down evenly.
Step 2: Mask the face and warm your cans
Cut a cardboard mask roughly the shape of the body and hold it above the face, not flat on it. Sitting the mask about half an inch (13 mm) above the surface lets the edge color drift under it slightly and feather in, instead of leaving a hard cut line. Tape off any binding you want to keep clean.
Before you spray, stand your aerosol cans in warm water for a few minutes. Warm lacquer sprays finer and is far less likely to spit or clog, which matters a lot when you are trying to lay down light, even passes.
Step 3: Spray the dark edge first
Start with the darkest color on the back and around the edge of the body. As you come near the face, hold the can well back from the surface so the color lands as a soft, feathered halo rather than a sharp band. Keep the can moving with even arm strokes and let the color build layer upon layer. Spray quickly and lightly. It is far easier to add another pass than to lift color you have already piled on.
Step 4: Lay the amber base
Once the edge is set, spray your amber toner over the face with light, even arm movements, feathering in from the edges to give even coverage across the top. Do not try to cover the guitar in one go. If you spray heavy and wet, the color floods and your stain underneath can run. Thin passes, allowed to flash off between coats, keep the amber clean and even.
Step 5: Build the gradient with tobacco
Now dial in the burst. Spray the tobacco toner working from the middle of the guitar out toward the edge, building the warm band that marries the bright amber center to the dark rim. Keep moving out and back, adding light passes, until you are happy with the gradation of color. Stop and look at the body in good light often, because the gradient reads differently under clear coat than it does dry.
For a 2-tone burst, skip this step and let the amber center fade straight into the dark edge from Step 3.
Step 6: Clear over the burst
The clear coat protects the burst and brings out its depth. Apply anywhere from 5 to 10 clear coats, and sand lightly between coats to knock down any runs or bumps. Build the clear slowly. Because the toner underneath is translucent, sanding too hard will cut straight through the clear into your color, and that is very hard to fix.
When the clear is fully built and cured, level and polish it. Work through progressively finer wet-and-dry sandpaper, using a lighter gauge each time to remove the scratches left by the last one. Soaking the wet-and-dry paper in water for about an hour before you use it helps it cut cleanly. Finish by buffing to a gloss. The painting tutorial covers the full rubbing-out and polishing schedule.
Rattle cans vs airbrush, honestly
The method above uses aerosol cans (rattle cans), and it genuinely works. It is how most home builders get a great burst without buying more gear. The trade-off is control: a can gives you a fixed spray pattern and pressure, so your feathering comes entirely from distance and from how fast you move your arm.
An airbrush gives finer control over the fade, because you can dial the paint volume down and get closer with a tighter pattern, which makes gradual transitions easier. It also costs more, needs a compressor, and has a learning curve of its own. If you already own one and can spray thinned lacquer safely, it will reward you on the gradient. If you do not, do not let that stop you. A patient hand with warm cans and light passes beats a rushed airbrush every time.
Whichever you use, the rules are the same: thin coats, keep the can or brush moving, and build the color up gradually.
Classic burst failures and how to prevent them
Hard edge instead of a soft fade. Usually caused by holding the can too close, laying the mask flat on the body, or spraying too heavy at the rim. Prevention: keep the mask about half an inch off the face, hold the can farther back as you near the edge, and build the dark in light passes so the transition stays soft.
Overspray muddying the center. The bright center goes dull and brown because stray dark color has drifted into it. Prevention: always spray the edge from the outside in, aim your dark passes at the rim rather than across the top, and check the center often. Keep the amber center as clean and light as you can.
Uneven halo. One side of the burst ends up wider or darker than the other. Prevention: work in even arm strokes all the way around, rotate the body as you go so you are always spraying from a comfortable angle, and step back frequently to judge the whole burst rather than one section. Balance it while the color is still light, because it only gets harder to even out as you build.
When to stop and ask
If the burst goes wrong, or you sand through your color or veneer, stop before you make it worse.
