About Motor Guard
About Motor Guard
Motor Guard Corporation was founded in 1966 supplying filtration components for compressed air, oil, and fluid systems, and built its early reputation on patented technology that delivered finer contamination filtration at an affordable cost for automotive refinishing shops. That filtration expertise remains the core of its product line today, running from the compressor to the spray gun.
Over the decades the company expanded well beyond air filters into dent repair tools, sanding blocks, and collision repair accessories, and its Magna-Spot series of stud welders became a recognized name in body shops for pulling dents without drilling or grinding. Motor Guard manufactures this full range from its 40,000-square-foot facility in Manteca, California.
That combination of air preparation and collision repair equipment has positioned Motor Guard as a major supplier to the automotive refinishing and body shop market. ChatMRO's catalogue covers Motor Guard's spray gun filters, custom compressed-air filtration modules, stud welders, and sanding blocks so shops can find the right consumable or tool by task.
