The Spray Bike Frame Builder's Transparent Finish 400ml in Matte is a clear protective aerosol top coat designed to seal and protect painted bicycle frames with a flat, chalk-like finish. Whether you've just finished a colour coat in one of the Spray Bike paint collections or applied a layer of Frame Builder's Metal Plating, the Transparent Finish is the final step in a professional, durable frame finish.

The water-based formula bonds directly to bare steel, aluminium, carbon, and painted surfaces — compatible with the full Spray Bike range. It locks the paint beneath against UV fading, moisture, and the wear of everyday riding while maintaining the completely flat aesthetic that many custom builds are known for. Apply in light, even coats from 20cm or more, and allow the frame to cure fully before returning to use.

The Matte Transparent Finish is the option for riders who want to preserve the flat, understated look of a matte colour coat — keeping everything clean and minimal without any sheen or reflection. For a satin or gloss finish, the Satin/Gloss variant is also available.

As part of the Spray Bike Frame Builder's system, Transparent Finish works alongside the Metal Primer, Carbon Primer, Cold Zinc, Smoothing Putty, Metal Plating, and the full range of Spray Bike colour collections to give you a complete frame-building workflow in aerosol form.
