Source Chemical Purple Clay Bar 200g Heavy Duty
The Source Chemical Purple Clay Bar is the heavy-duty clay detailers reach for when a regular bar can’t break through. This 200g purple clay bar is an aggressive, heavy-cut grade made in Japan, built for paint overspray, industrial fallout, tree sap, rail dust, and other bonded contaminants that ride out a normal wash. One 200g bar goes a long way, so a busy shop can work through several cars before it needs another.
Clay works by grabbing whatever is stuck on top of the paint. As the bar glides over a lubricated panel, it pulls bonded particles out of the clear coat and holds them inside the clay, so they don’t get dragged back across the surface. The Source Chemical Purple Clay Bar is firmer and cuts harder than a medium bar, which is why it clears heavy contamination in fewer passes.
Is the Source Chemical Purple Clay Bar the Right Grade for Your Car?
Purple is a heavy cut, never a medium cut. Because it’s aggressive, the purple clay bar can leave light marring, and you’ll see it most on dark-colored cars, so plan on polishing after you clay. Most of the time a one-step polish like 3D ONE Hybrid One Step Compound is all it takes.
If the paint only has light to medium contamination, the Source Chemical Gray Medium 200g Clay Bar is the better pick. The gray bar doesn’t mar the paint on its own. The two bars are alternatives for different jobs, not a two-step combo, so pick the one that matches how dirty the paint really is.
What makes this one worth keeping in the garage:
- Heavy-cut purple grade for serious bonded contaminants
- Removes primer and paint overspray for auto body and paint shops
- Saves time for high-volume reconditioning shops and dealer prep
- Large 200g bar that can be cut into smaller working pieces
- Covers big surfaces fast on boats and RVs
- Made in Japan, like every clay bar Hot Wax Garage sells
How to Use the Source Chemical Purple Clay Bar
- Wash and dry the car first. 3D Pink Car Wash Soap takes off the loose dirt so the clay only has to deal with what’s bonded. If the paint has iron fallout, spray 3D BDX Iron Remover before you clay.
- Cut the 200g bar into two to four pieces. Knead one piece into a flat patty about the size of your palm. If a piece hits the ground, throw it away; grit in the clay will scratch the paint.
- Work one small section at a time, about 2 x 2 feet. Spray plenty of lubricant, such as Hi Tech Wax Enhancer & Clay Lube. Never clay a dry panel.
- Glide the Source Chemical Purple Clay Bar back and forth with light pressure and let the clay do the work. When it moves smoothly and quietly, that section is clean.
- Fold the clay to a fresh side whenever it looks dirty, then wipe the section with a clean microfiber towel.
- Polish the paint to take out any light marring, then protect it with a wax, sealant, or coating.
Tip: Keep plenty of lube on the panel the whole time. With a heavy-cut bar like the Source Chemical Purple Clay Bar, more lube means less marring and less polishing afterward.
For heavier defects after claying, step up to 3D ACA 500 X-Tra Cut Compound or 3D ACA 510 Premium Rubbing Compound. For a softer bar, go with the Source Chemical Gray Medium 200g Clay Bar or the Magna Shine Clay Bar. We only carry clay bars that are made in Japan.
