The HVLP (High Volume Low Pressure) spray gun is the industry standard for achieving a beautiful finish with high material transfer efficiency. However, simply spraying paint isn’t enough. Properly tuning your professional spray gun and its spray gun accessories is the key to minimizing overspray, reducing material costs, and laying down a perfect coat.
A mirror-like paint finish is the ultimate goal of any auto refinishing job—and it’s not just about expensive products. Industry experts agree: 40% of the result comes from polisher power, 35% from pad selection, and 25% from technique. Yet a 2024 survey of 1,000 auto technicians found that 67% use the wrong polisher-pad combo, leading to dull finishes, swirl marks, or even clear coat damage.
Automotive refinishing is a precision craft where success is determined long before the first coat of paint is applied. Industry research from the International Auto Refinish Association (IARA) reveals that 70% of post-repair paint failures—including peeling, blistering, and uneven gloss—trace back to inadequate pre-sanding preparation.
A flawless paint job is won or lost in the preparation phase, and sanding is its cornerstone. Even with the best polishing tools and spray guns, improper sanding will telegraph through every layer, ruining the final result. As experts in automotive abrasives and tools, we see these five common mistakes most often. Avoid them to ensure efficiency and perfection in your shop.
