Removing Dents Using Glue Pulling
Did you know we can use GPR on aluminium panels too?
A GPR (Glue Pull Repair) on aluminium is carried out slightly differently than a panel made of steel, and the main factor is the temperature.
First, the panel is polished and cleaned with isopropyl alcohol to remove any impurities, to give the best adhesion for the glue, as any standard glue pull repair would be carried out.
This is where we make the changes. As aluminium dissipates heat 15 times faster than steel, a heat gun is set up so a constant flow will be put into the surrounding area. When carrying out the repair, the panel temperature is kept to around 30-35 degrees. This is so the panel becomes more pliable, and helps with the pulling of the dent.
Another heat-related point to make is the choice of tab we use.
We use the Keco Dead Centre Blue tabs, as the material they are made of “keeps in” the heat longer than the more rigid Ice tabs for example, so the panel, glue and tab are relatively the same temperature when the pull is made. All these factors combined give us the optimum environment for the best results for glue pulling aluminium!
