The 6C Process
Maximize your Glue Pull Repair results with KECO’s application-based process for controlling the repair environment, improving adhesion, and building a more efficient path to paint.
Built for Better GPR Results
Successful glue pulling comes from more than just having the right tools. The 6C Process helps technicians build a repeatable repair approach by checking the repair area, choosing the right setup, preparing the surface, applying glue correctly, correcting the damage, and continuing into conventional repair or refinishing.
Before You Begin
The following steps are designed to be applied to a prewashed vehicle. Always check OE procedures before beginning any repair.

Already familiar with GPR? Go straight to the part of the process you need.
Check
- Always check OE procedures before starting any repair.
- Check substrate and material type.
- Fully check the extent of damage. An inspection lamp is recommended.
- Check panel temperature and address extremes with heating or cooling.
- Turn on glue gun and set temperature to 385°F / 195°C. Dispensed glue should be smoking hot, but not boiling.
Essential for fast, efficient adhesion during GPR while utilizing the KECO 6C Process.

Shop Now →Choose
- Select a tab shaped to match the dent or bodyline.
- On steel, tabs should fit within the edges of the dent so secondary damage remains visible.
- On aluminum, flexible tabs often provide the best results by aiding adhesion without locking in crowns.
- Select a pulling tool based on the amount of precision and control required.
- When possible, use a lifter where the feet hold down and control the surrounding metal.

Shop Now →Clean
- Use a cutting compound by hand or machine to remove stubborn contaminants or wax coatings.
- Thoroughly clean the panel with minimum 95% Isopropyl Alcohol. 99% is ideal.
- Thoroughly clean the tab surface with minimum 95% Isopropyl Alcohol. 99% is ideal.
Specifically designed for GPR and the KECO 6C Process to promote strong pulls, proper surface preparation, and easy glue release from panels and tabs.

- Heat the panel surface to 120°F / 50°C.
- Flash the tab surface with a heat source.
- Fill the tab surface entirely with glue.
- Place the tab on the panel without forcing glue out from the tab.
- Look for a visible bead of glue surrounding the tab edge.
- Fill any surrounding gaps directly with hot glue from the glue gun.
- Wait for the glue to properly set before pulling.
High-strength slow acting glue designed for large and complex dents, providing longer working time for multi-action pulls.
Shop Now →Fast and stiff glue ideal for smaller dents, shorter pulls, and faster repair cycles.
Shop Now →Correct
- Use an infrared thermometer to verify an optimal glue pulling temperature of 85°F / 29°C around the bond line before pulling.
- Set your pulling device and begin the correction process.
- Use the double-action process whenever possible by applying slight upward tension to the tab while controlling surrounding metal movement.
- Knock down highs with selected knockdown tools to restore original panel tension and improve metal flow.
- Check spent glue for insight into pulling temperature and adhesion performance.
Control highs, manage metal flow, and refine repairs with KECO’s assortment of knockdowns, slappers, hammers, and blending tools designed for GPR and collision repair applications.

- Repeat KECO’s 6C Process until large damage reduces and reaches the desired panel flatness.
- Prepare for filling, checking technical data sheets for today’s filler requirements.
- Sand, repaint, and finish the repair.
- Skim it, sand it smooth, prime it, and paint it.
