SCHEDULE A CONSULTATION

I've done up a demo video on how I install spray chines.
This particular clip shows how its done on an older 4.55.
There is a bit of tweaking from a 450 template and the end result is a nice matching contour to suit.
@suns.welding is currently in Brisbane and can come install a set in your shed or driveway 😎

This video showcases the complete process of fabricating and plastic extrusion welding custom spray deflectors (chines) onto a Polycraft boat.

The vessel is manufactured from rotomoulded LDPE (Low-Density Polyethylene), a highly durable and impact-resistant material that allows for a range of structural modifications. In this demonstration, we design, fabricate, and weld new spray deflectors to enhance ride quality, reduce water spray, and improve overall on-water performance.

From preparation and fit-up through to final extrusion welds, this video highlights the techniques, equipment, and attention to detail required to achieve a strong, clean, and long-lasting result.

Did you know...
We use the same UV-stable polyethylene as the Polycraft hull for spray chines?
That means a perfect match and welds that last!

Just wrapped up a repair on a Polycraft 4.5 Drifter for @billsmarinecairns
The previous weld didn’t hold up, letting water sneak in where it shouldn’t!

At Sun's Welding, we don’t just patch things up; we get it right the first time. After carefully removing the old weld, we prepped the polyethylene surface and applied quality welds to ensure a perfect, watertight seal.

Now this boat’s ready for the rough waters again—no leaks, just solid craftsmanship! 🌊

Need a top-quality repair? Trust the experts who know boats and plastic welding.

🚤 Hull Repairs Done Right!

A 5.99 Polycraft Frontier owner came to us with a leaky problem—an earlier repair had failed to fuse properly, letting water seep into the hull. 💧

At Sun’s Welding, we don’t cut corners. We removed the subpar weld, thoroughly prepped the surface to eliminate oxidized polyethylene and saltwater contamination, and applied multiple weld runs with the right combination of heat and pressure.

The result? A watertight, durable repair that’s built to last and ready to tackle the waves! 🌊

If your Polycraft or polyethylene boat needs professional plastic welding, we can bring it to your doorstep!

📍 Townsville

We’re so grateful to the amazing customers who trusted us with their projects. Despite one rainy reschedule, this journey was a massive success! 🌧️➡️☀️

🌟 Spot the Difference! 🌟

Left: A previous repair.
Right: A Sun's Welding repair.

💡 We use matching materials for filler to ensure longer-lasting, durable repairs.

🚨 Why it matters:
Using high-density filler on low- or medium-density polyethylene (like rainwater tanks) can lead to cracks or failure under stress from water pressure, temperature changes, and UV exposure.

🔧Trust Sun’s Welding for expert mobile welding done right the first time.
