About Us

Built for Those Who Know the Difference.

International Epoxies & Sealers (IES), also known as Busch Manufacturing Company, was founded in 1985 by Steven Busch in Largo, Florida. Today, we proudly operate from San Antonio, Florida, remaining a family-owned and operated business led by Steven Busch and his son, Ben Busch.

From the beginning, our mission has been simple: provide professional-grade products that deliver exceptional performance and value. While others focus on building brand recognition, we've focused on building products that earn their reputation through consistent results in the field.

Almost all of our products are proudly manufactured in the USA, allowing us to maintain the quality, reliability, and standards our customers expect. For more than 40 years, we've worked alongside automotive refinish professionals, shop owners, distributors, technicians, and DIY'ers who understand that real value isn't determined by a logo—it's earned through performance.

We believe the best products are the ones that help our customers succeed. That's why our goal has always been to provide top-of-the-line solutions at a greater value than our competitors. When our customers become more profitable, we prosper together.

The professionals who choose IES know the difference between products that simply look good on paper and products that perform when it matters most. They understand that protecting profitability doesn't mean sacrificing quality. They value dependable products, honest service, and long-term relationships.

At IES, we're committed to delivering both. No gimmicks. No inflated pricing. No shortcuts. Just products designed to perform and a team dedicated to supporting the people who use them every day.

Most importantly, we want every customer to have the best experience possible with our products and our service. We will do everything we can to ensure your success and earn your trust.
