Summer Advanced Wet Sanding Training

3-Day Intensive | May 22-24 | Carol Stream, IL

Hosted at the Gloss University Studio in Carol Stream, Illinois, this three-day advanced wet sanding class is limited to just four students for a focused, hands-on learning experience.

Designed for experienced detailers, this training takes a deep dive into the multi-stage wet sanding processes used to achieve true show-car results. Over three full days, students will work as a small group on a recently restored vehicle, learning how to safely level, refine, and correct premium paint systems at a professional level.

Class Schedule & Arrival

Class Time:

• Day 1: 9:00 AM – 5:30 PM

• Day 2: 9:00 AM – 5:30 PM Extended as needed

• Day 3: 9:00 AM – 5:30 PM

Students are asked to arrive 15 minutes prior to the start of each day to get situated and ready to begin on time.

What You’ll Be Working On

The subject vehicle for this class is a 25-year-old, recently restored car finished in premium high-solid paint with multiple coats of clear coat. This platform allows students to experience how advanced sanding techniques interact with modern paint systems while working toward a high-level, show-quality finish.

Throughout the weekend, students will follow the vehicle through a multi-stage sanding and refinement process, gaining real-world experience that directly translates to restoration, correction, and high-end detailing work.

Training Breakdown

Day 1 – Theory, Tools & First-Stage Sanding

The class begins with a strong technical foundation before moving into hands-on work.

Morning Session:

• Sandpaper types, grit selection, and sanding blocks

• Hard blocks vs. foam blocks and proper use cases

• Overview and history of modern paint systems

• Live Q&A to prepare for hands-on sanding

Afternoon Session:

• Begin the first stage of sanding as a group

• Learn proper technique, pressure control, and surface evaluation

Day 2 – Advanced Sanding & Process Execution

Sanding work continues throughout the day with a focus on:

• Multi-stage sanding progression

• Dry sanding vs. wet sanding

• Reading scratch patterns and surface texture

• Understanding how different grits behave in real-world conditions

Due to the labor-intensive nature of advanced wet sanding, we anticipate Day 2 may extend slightly beyond the scheduled end time. This ensures each stage of the process is completed correctly without rushing.

Following the conclusion of Day 2, students will head to a group dinner, providing an opportunity to relax, discuss the day’s work, and continue learning in a more informal setting.

Day 3 – Paint Correction & Refinement

The final day transitions into correcting and refining the sanded surface.

Topics include:

• Rotary polishing fundamentals and benefits

• Wool vs. foam pads and their roles in correction

• Technique, pressure, and cycle time management

• The importance of proper lighting during paint correction

Students will see how proper sanding sets the foundation for efficient, high-level paint correction and final refinement.

Important Class Disclaimer

This is not a beginner-level class.

Students must have prior experience with machine polishing and feel confident operating polishing equipment.
No sanding experience is required; however, a solid understanding of paint correction fundamentals is expected.

Why This Training Is Different

• Limited to 4 students for maximum hands-on time

• Real vehicle, premium paint system, real results

• Advanced techniques rarely taught in group settings

• Focused on precision, control, and professional execution
