Why choose a tru oil finish on guitar?

Pros: easy hand application, no spray equipment, warm “natural wood” look, great feel on necks, simple spot repairs.
Cons: slower build than spray finishes, needs patience for thin coats and drying, and ultra-glass “piano gloss” requires more levelling/polishing.

Buy by workflow (tru oil guitar finish steps)

1

Sealer & Filler (Prep + Base)

Prepares the wood by sealing and helping fill pores (open-grain woods).
Shop Sealer & Filler basecoat → Acts like a sanding sealer + pore filler in one. Very open-pore woods may need extra applications.

2

Colour with Dye / Stain (optional)

For transparent / translucent finishes: alcohol/ethanol dye or metal complex dye.
Shop dyes & stains → Apply, let dry, then build your oil coats over the top.

3

Build the Finish (Thin Coats)

Apply multiple thin coats to build protection and depth (body or neck).
Shop the oil finish (90ml / 240ml) → Thin coats dry cleaner and reduce streaks. Lightly level between coats if needed.

4

Stock Sheen & Conditioner (Sheen Control)

Shop Stock Sheen & Conditioner → Refine the final feel and sheen — dial in a tru oil satin finish or a soft gloss — and condition the surface.
Great for dialing-in a smooth “played-in” feel, especially on necks.

Optional add-ons (recommended for finishing a guitar with tru oil)

A tru oil wood finish is forgiving, but good prep and clean application make a big difference. These add-ons help you get a smoother finish with less effort.

Prep & Sanding

Better sanding = cleaner oil finish. Essential for a smooth neck feel.

Level, Polish & Buff

For high-gloss: level, polish & buff instead of the sheen and conditioner product for mirror depth. (A tru oil finish can reach a high gloss, but it takes patience and proper curing time.)

Care & Maintenance

After finishing: fretboard oil and long-term care.

Quick FAQ

Does this category include a complete finishing solution?

Yes. Sealer & Filler prepares/seals the wood, the oil finish builds protection, and Stock Sheen & Conditioner refines the final sheen and feel. They’re selected to be fully compatible.

Does Sealer & Filler replace grain filler or sanding sealer?

It acts as both: it seals like a sanding sealer and helps fill pores on open-grain woods. On very open-pore woods (e.g., some ash/mahogany), you may need extra applications to get a perfectly level surface.

Which size should I choose (90ml vs 240ml)?

90ml is usually enough for a neck or a small project. 240ml is better for full bodies, multiple builds, or if you want extra coats and a deeper finish.

What are the key safety tips when finishing a guitar with tru oil?

Apply very thin coats with good ventilation, avoid skin/eye contact, and dispose of oily rags safely (do not ball them up; let them dry flat or store in a sealed metal container).
