In any repair or refinishing job, the final result is only as good as the preparation. Whether you're in a professional body shop or working on a personal project, every stage of the process matters—from surface prep and filling, to degreasing and clear coating. At Sunmight UK, we offer a full range of premium products designed to help you deliver a clean, durable, high-gloss finish every time.
Here's a breakdown of our top-performing fillers, thinners, and clear coats—and how each one fits into a professional workflow.
Start Strong with the Right Body Filler
One of the first steps in any repair is filling. Using a reliable, easy-to-apply filler ensures a smooth surface and saves you valuable time during sanding and shaping.
RJ Max Lightweight Body Filler
This high-performance lightweight filler is a firm favourite for a reason. It spreads smoothly, cures quickly, and sands down easily, giving you a clean, even surface to work on. Perfect for medium to large surface repairs, it also offers excellent adhesion on metal and fibreglass.
RJ Fibreglass Filler
When more structural reinforcement is required, our fibreglass filler is ideal. It’s reinforced with short-strand fibres to provide additional strength and rigidity. It's well-suited for bridging larger gaps or dealing with more demanding repairs, while still sanding to a smooth finish.
Both fillers are supplied with hardener and are easy to mix and apply—giving you full control from the start.
Proper Surface Prep Makes All the Difference
No matter how good your filler or paint system is, if your surface isn't clean, your finish won’t last. Grease, wax, and contaminants can all lead to adhesion issues, fisheyes, or peeling.
RJ Degreaser
Our fast-acting panel wipe is formulated to effectively remove grease, silicone, and wax from all types of surfaces before painting. It evaporates cleanly, leaving no residue behind. Whether you’re preparing a new panel or refinishing a repair, RJ Degreaser ensures a clean base for your filler, primer, or paint.
Finish with Confidence Using a High-Quality Clear Coat
Once you’ve prepped and painted, a good clear coat is what takes your work from decent to professional-grade. You want gloss, depth, durability—and you want it without the stress.
X50 Express VHS Clear Coat Kit
This clear coat is a favourite among trade professionals who need performance and efficiency. It’s fast-drying, high-gloss, and designed for excellent flow and levelling. The X50 offers excellent chemical and weather resistance, making it ideal for everyday repair jobs or full resprays. Because it cures quickly, it also helps reduce booth times and improves throughput—without compromising on finish.
The kit includes both the clear coat and hardener, making it a convenient, cost-effective choice for busy body shops.
