How long will the vinyl overlay last?

Our products are made using the highest quality automotive grade vinyl with a average life span of between 3-5 years, depending on aftercare and conditions to which the vinyl is commonly exposed to.

I'm not confident installing it myself – what should I do?

No worries at all! Our kits are designed for easy DIY installation, and we provide step-by-step instructions and videos to guide you. But if you'd prefer a professional touch, we recommend checking out our Installer network to find one close to you. If located in Sydney you can book in directly with us via the "Book Install" button on the menu bar.

What if I mess up my install?

Don’t stress — it happens! We understand vinyl can be tricky to work with sometimes, so rest assured if you have trouble or ruin a piece/part of your kit we will happily provide a replacement for only $1 plus the shipping cost* (terms & conditions apply).

Are the overlays removable? Will they damage my car?

Yes, all of our overlays are fully removable and designed with automotive-safe materials that won't damage your paint or factory badges when removed correctly. If you ever decide to take them off, simply apply gentle heat (like a hairdryer or heat gun) to soften the adhesive, then peel them away cleanly. No residue, no damage — just your original surface underneath.

Video Instructions

Prep

Thorough cleaning is required or else the vinyl will not stick. Use isopropyl alcohol to remove any coatings/wax. Dry the area completely with a microfibre.

Application

Partially peel the overlay from the backing and start by lining it up with one end of the trim you are applying it to. Gradually pull away the backing paper as you apply pressure to the vinyl securing it to the skirt skirt. Use a heat gun to lightly heat the edges down and push them in further with your fingers or a squeegee to secure sufficiently.

Finishing Touches

Trim away any excess vinyl at the edges for a seamless finish. To further assist the vinyl in adhering you can lightly apply heat with a heat gun or hair dryer. Contact us if you have made a mistake and we will happily provide a solution.
