Materials Guide

Choosing the right material for an auto upholstery job is half the decision. The material determines how the interior looks, feels, wears, and ages. This page covers the options we work with most frequently, their strengths and trade-offs, and situations where one material clearly beats another.

Leather

Leather is the premium choice for auto interiors and the most requested material in our shop. Not all leather is equal, though, and understanding the grades matters.

Full-grain leather

The highest quality. The entire grain surface of the hide is intact, with no sanding or buffing. Full-grain leather develops a patina over time that most owners consider an asset rather than a flaw. It is the most durable grade, the most breathable, and the most expensive. You will find it in high-end European cars and in restorations where the owner wants the best available material.

Top-grain leather

The outer layer of the hide, sanded lightly to remove imperfections and then finished with a protective topcoat. This is what most factory leather seats are made from since the mid-1990s. It is more uniform in appearance than full-grain, easier to clean, and still very durable. The majority of our leather re-cover jobs use top-grain hides.

Corrected-grain leather

Heavily sanded and then embossed with an artificial grain pattern. The surface is uniform but lacks the natural character of full-grain or top-grain. Common in mid-range vehicles. It holds up reasonably well but does not age as gracefully.

Split leather and bonded leather

Split leather is the inner layer of the hide after the top grain has been removed. Bonded leather is reconstituted from leather scraps and adhesive. We do not recommend either for auto seating. Both wear poorly, crack easily, and peel within a few years of regular use. If your budget does not stretch to top-grain or full-grain, good-quality marine vinyl will outlast bonded leather by a wide margin.

Vinyl

Vinyl is the workhorse of auto upholstery. It is cheaper than leather, easier to clean, resistant to water, and available in a huge range of colours and textures. Modern automotive vinyl has come a long way from the stiff, shiny material that baked you in a 1970s car.

Marine-grade vinyl (brands like Sunbrella, Naugahyde, and SpradlingVinyl) is what we use for seats that will take heavy wear, direct sun, or moisture. It is UV-stabilised, mildew-resistant, and rated for outdoor use. For boat seats and vehicles that spend time outdoors, marine-grade vinyl is often the best value for money.

Standard automotive vinyl is suitable for door panels, headliners, and areas that do not take body contact. For seats, we always recommend stepping up to marine-grade if vinyl is the chosen material.

Canvas and cloth

Canvas and woven cloth have a place in specific builds. Jeeps, trucks, and off-road vehicles sometimes look better with a heavy canvas seat than with leather. Cloth breathes better than vinyl in hot climates. The downside is that cloth stains more easily and is harder to keep clean.

For convertible tops, canvas (sometimes called duck) is the traditional material. Modern convertible top canvas is typically an acrylic-coated fabric (like Haartz Stayfast or Twillfast) that looks like cloth from the outside but sheds water and resists UV. These materials last 8 to 12 years under normal conditions.

Convertible top materials

When replacing a convertible top, the material choice breaks down into a few categories:

Marine-grade options

For boat work, the material needs to survive constant UV, salt spray, moisture, and mildew pressure. Marine-grade vinyl is the standard here. We use fabrics rated to ASTM weathering standards with UV inhibitors built into the material rather than applied as a surface treatment.

Thread matters too. We use UV-resistant polyester thread (Tenara or similar) for all marine work. Standard cotton or nylon thread will rot within a year or two in a marine environment.

Choosing the right material

There is no single best material. The right choice depends on the vehicle, the budget, the climate, and how the vehicle is used. If you are unsure, bring the car to the shop or send us photos and we will suggest options based on what we have seen work for similar vehicles.
