We do our very best to remove support marks but some fine sanding may be required. All pieces and parts come unprimed and unpainted with all supports removed. Please do bear in mind that resin can be quite delicate so try to avoid dropping your parts! Sadly, we can't be held responsible for breakages once your item has arrived.

Frequently Asked Questions – O Gauge / O-16.5 Diesel Heavy Oil Tank & Brick Bund

What exactly is included with this oil depot tank and bund set?

The set includes the resin-printed diesel heavy oil tank, the brick bund with containing wall and supports, the separate cap and vent pieces, and the figure shown in the product photos. All items are supplied unassembled, unprimed, and unpainted, ready for you to clean up, prime, and paint.

What scale is this model suitable for?

This model is designed for O gauge or O-16.5 layouts. It represents a diesel heavy oil storage tank on brick supports with a safety bund wall, ideal for depot or industrial scenes in those scales.

What are the overall dimensions of the bund and tank?

The brick bund is approximately 88 mm long by 67 mm wide and 15 mm tall. The oil tank sits inside the bund and is about 57 mm tall. These dimensions make it a compact but visually prominent feature on a depot or yard scene.

Is the model ready to use straight out of the box?

The model is ready for you to prime and paint, but it is not pre-painted or fully assembled. All supports are removed and the resin is cleaned and cured by hand. You may wish to do some light sanding to remove any remaining support marks before priming and painting.

Where is this model made and what material is used?

The model is printed in the UK using high-detail resin. Each piece is produced, cleaned, and cured by hand, giving you crisp detail suitable for close-up viewing on a layout or diorama.

Is the model durable enough for regular layout use?

High-detail resin gives you fine detail but can be delicate compared with injection-moulded plastic. It is perfectly suitable for layout use, but it should be handled with care and not dropped or subjected to heavy knocks, especially around finer parts such as the ladder, pipes, and lifting tags.

What should I do if the model arrives damaged in the post?

If your item arrives broken, please take clear photos of the damage and contact us as soon as possible. Breakages that occur after safe delivery (for example, from dropping the model) cannot be covered.

Why are there small marks or lines on the surface of the model?

Although supports are removed and the model is cleaned and cured by hand, some minor support marks or faint layer lines can remain. These are normal for resin prints and can usually be smoothed with a little fine sanding before priming.

My tank or bund looks slightly warped. Is this normal?

Slight variation can occur with resin parts, especially if exposed to heat or direct sunlight. If you notice minor warping, gentle warming (for example, in lukewarm water) and careful, gradual bending can sometimes help, but always proceed cautiously. If the model arrives significantly distorted, contact the seller with photos.

The ladder or pipes arrived bent or slightly out of shape. Can they be fixed?

Fine parts like ladders and pipes can sometimes flex in transit. You can often straighten them by gently warming the piece (for instance, in lukewarm water) and carefully easing it back into shape. Allow it to cool fully in the corrected position before handling further.

The cap or vent does not seem to fit properly. What can I do?

Because the cap and vent are separate pieces to aid painting, a tiny amount of adjustment may be needed. Lightly sand the mating surfaces or the peg/slot areas until the fit is snug but not forced. Once you are happy with the fit, glue them in place after painting or dry-fitting.

There are small chips or rough spots on the brick bund. How should I fix them?

Minor chips or rough areas can be smoothed with fine-grit sandpaper or small needle files. After sanding, brush away dust and apply a suitable primer. Any tiny imperfections can be filled with a small amount of model filler or thick primer before your main paint coats.

How should I attach the cap and vent to the tank?

Test-fit the cap and vent first to ensure you are happy with their orientation. Many modellers prefer to paint these parts separately, then glue them in place with a small amount of cyanoacrylate (super glue) or another suitable model adhesive. Avoid excess glue to keep the detail sharp.

What type of primer should I use on this resin model?

Use a primer specifically suitable for resin or general-purpose plastic model primer. An aerosol or airbrushed primer gives an even coat and helps paint adhere. Apply several light coats rather than one heavy one, allowing each coat to dry fully before proceeding.

Do I need to wash the model before painting?

Although the parts are cleaned and cured by hand, it is good practice to give resin models a quick wash in lukewarm water with a drop of mild detergent. Gently scrub with a soft brush, rinse thoroughly, and allow to dry completely before priming.

How can I paint the brick bund to look realistic?

Start with a brick-red or brown base coat, then pick out individual bricks in slightly different tones for variety. Once dry, apply a thin mortar wash (a light grey or off-white thinned with water or medium) and wipe back the raised brick faces. A final dry-brush with a lighter shade will bring out the texture and edges.

What colours work well for the oil tank itself?

Common choices include industrial greys, dark greens, or weathered off-whites, depending on your era and region. After the base coat, add subtle rust streaks around seams, lifting tags, and the ladder, plus some darker staining near the pipes to suggest oil spills and grime.

How should I paint and attach the figure?

Paint the figure separately from the tank and bund for easier access to details. Use a fine brush and thin coats, starting with clothing base colours, then adding shading and highlights. Once fully dry, fix the figure in place with a small dab of suitable glue in your chosen position within or near the bund.

Any tips for weathering the bund and surrounding area?

Use thin dark washes to suggest oil staining inside the bund and around the base of the tank. Add subtle green or brown tones for dampness and grime along the lower brickwork. A little pigment powder or dry-brushed dust colour on the top edges and ground around the bund will help it blend naturally into your depot scene.

When should I glue everything together during painting?

It is usually easiest to:

  • Clean and lightly sand all parts.
  • Prime the tank, bund, cap, vent, and figure separately.
  • Paint and weather each component.
  • Dry-fit to check alignment.
  • Glue the cap, vent, and figure in place once you are happy with the finish.

This approach keeps access to detail areas and reduces the risk of stray glue marks on painted surfaces.
