Spraying a Les Paul Junior Vintage Sunburst

The reason for doing this job was that I have not been able to find any other information about recreating this particular finish.

I’ve been fortunate to be able to examine a number of mid/late fifties Gibson guitars to see how they were painted and here I’ve attempted to re-create that using aerosols (of course!)

The first step in any finish is to sand the wood well, then fill the grain. I’m using Rustins grain filler but have darkened it by adding some burnt umber pigment to replicate the dark filler found on these guitars.


The trick to grain filling is to pack it well into the pores by applying with the grain then remove as much as possible from the surface by scraping across the grain. Hardened filler is very difficult to sand off, so it’s best to remove as much as possible from the surface.

Once the grain filler has been sanded smooth, the next step is sealing the wood. I like to quite a lot of sanding sealer on, then once dried overnight (or longer) sand it back good and smooth.

Once the sealer coat is good then the fun begins.

The base layer of the burst on the front is a bright yellow. I’ve used, appropriately enough, my Bright Yellow lacquer for this job. I masked everything but the face of the guitar and got a good few coats on there. Once dried, i feathered the edges at the edge radius, to give a nice smooth transition. Where I sanded through the sealer coat I applied more sealer. Once dry I masked the fretboard edges and face ready to spray the burst.

For the edge of the sunburst, I’ve used a colour very similar to my Tobacco Brown, but containing a touch more red to replicate the transition of the burst found on some fifties juniors. The actual colour seems to vary between original guitars from reddish to practically black.

Spraying vertically (or maybe outwards a little) leaves the sides almost untouched. The bass side of the neck heel gets a bit of brown and maybe this is why the heel of these guitars is almost always sprayed with this opaque brown. Or maybe it’s to hide a less than perfect neck joint. Either way, I did the same.

The back and sides of the body and the back of the neck are sprayed in a transparent brown. My Medium Brown is a good match.

The next step is to blacken the peghead face. I close masked the edges of the headstock and sprayed a few heavy coats of black. Where the masking tape peeled away slightly I scraped the edge to a nice clean line.

The final step is clear coating. I’m using a Vintage Amber Tinted lacquer to replicate years of aging.

Still undecided whether to distress it or not.

  1. Could you possibly give me the name of the paints you used for the yellow part of the sunburst and the outside of the sunburst. Thanks as I’m making one myself

    • The centre is Bright Yellow and the edge a colour not yet offered which I’m calling “Nut Brown”. If you’d like a can, please order Tobacco Brown and make a note on the order for me to substitute.

      • thank you sooo much its great to find a place with everything straight away. i will be buying the paint in the next few months as im buying the gears for music jr guitar kit. im trying to replicate billie joe armstrong from green days guitar. i was wondering if you knew and had the colour for the back of the jr. its kind of dark reddish but its also a little light. thanks

        • Yes of course. The back, sides and neck is finished in my Clear Medium Brown lacquer. You can spray as light or dark as you wish, the colour gets darker the more coats you add.

    • Thanks, pretty much yes. I did spray the final clear coats using a compressor and spray gun because it’s faster but the burst on the front is 100% aerosols.

  2. Hey there, could you explain a general step by step of your manual technique to spray that burst freehand using rattle cans? Did you use and masking at all?

    • I used no masking, I find it leaves a hard edge. I practice going round the curves on an MDF template first then spray the body freehand, up close.

      When the weather’s better I’ll video a sunbursting demo on a guitar body I have here.

  3. It looks great, is that just 2 colours? The reddish fade is down to the thinner coats of the brown at the transitions?

    I am trying to bring my first ever electric back to life and would like to try to recreate the original sunburst as best I can, is this something a patient and dedicated idiot could manage?

    • Yes just two colours. The brown has two components though which is why it looks red at the transition.

      It’s not difficult if you take time and have patience but suggest you practice the sunburst on a piece of MDF or plywood first.

  4. I would be really interested to hear more about your spraying technique. Are starting barely overlapping and far back to get a more subtle transition, with extra coats closer up to make the edges opaque? I’ve seen a lot of aerosol videos and the bursts just seem so abrupt and ‘banded’. I’m looking at bursting a dark tobacco over transparent amber, but was thinking a broader cherry burst endernesth would be a nice transition. Now I’m thinking this brown is maybe a simpler approach. Does the brown layer to fully opaque?

    • Yes the brown is opaque when sprayed thickly enough.

      The sunburst is made with just a few close, fast passes of the aerosol. I use an MDF dummy body to practice the curves first!

  5. The yellow seems to be a very bright straight yellow and then once the brown is on it seems to have gone a more amber yellow color. How did you get the yellow to go amber like that? Or is it an illusion
