Pro APC Rig | Carton EP.03 Electric Sprayer + Bilt Hamber Surfex-HD
Pro APC Rig
The all-purpose-cleaner setup that does the whole car — and the shed.
An APC is only as good as how accurately you can dilute it and how evenly you can lay it down. Most people mix one strength in one bottle and use it on everything, which means it's too weak for the engine bay and too strong for the door cards.
BILT HAMBER SURFEX-HD
A water-based APC and degreaser from the most evidence-driven company in car care — Bilt Hamber publish their testing rather than their adjectives. Bilt Hamber state a working dilution range of up to 200-fold, which is what makes it the most flexible cleaner in the store: weak for interiors and trim, mid for pre-wash and door shuts, strong for engine bays and wheel arches. One bottle, one chemistry, three completely different jobs.
THE CARTON EP.03
A 2.5L cordless electric sprayer with a 60-minute runtime — motor-driven, so pressure stays constant from the first panel to the last instead of fading as your hand tires. Even coverage matters with an APC: patchy application means patchy dwell, and patchy dwell on a hot panel is how you get streaking.
