Ready for the First Glue Pull

Paint Condition, Clearcoat and Paint Thickness

Now that you have properly cleaned the panel surface the next step is to check the paint on the vehicle and paint thickness. Best method to inspect the paint first is with your PDR light, looking for signs of repaint. Example sanding marks, dirt in the paint are sure signs the vehicle has been repainted. Paint and clearcoat thickness. Using a paint thickness gauge is a great addition to your Glue Pull Repair kit. Knowing what to look for prior to glue pulling and if the paint is factory. Not all repaints will be easy to recognize by sanding marks and dirt.

Note: Repaints can be glue pulled with care and attention. Patience and the right glue and right glue temperature.


Panel Temperature

Panel temperatures and ambient temps always play an important role in successful glue pull repairs. Also humidity but with the right choice in glue you can have great pulls with the right panel temp and right glue temp. Always us a infrared temperature gun to check panels and even the tip of your glue gun for glue out of the gun temp. Glue gun temp dials are not showing you the temp of the glue out and going on a tab. Dealing with ambient temperatures is best to have a heat gun one to two feet away from the panel providing heat towards the panel while working. Keeping a constant panel temp of 75 to 80 degrees Celsius.

Glue Temperatures – At least 150 Degrees Celsius

Panel Temperatures – 75 to 80 Degrees Celsius

Types of Metal

Knowing what you are pulling first in types of metal. Steel sheet metal, Aluminum sheet metal and High Strength sheet metal. All can have successful glue pull repairs and some will require more heat then others, but we will get on that topic later. AHSS and UHSS. Within the collision repair industry, we use terms like advanced high-strength steel (AHSS), ultra-high-strength steel (UHSS), and Boron steel. AHSS and UHSS are used on the chassis and for closures and fasteners. Designers have to improve the crash resistance of the vehicles they are creating – specifically, the energy absorption of the steel structure – while keeping weight and material thickness under control. So yes, we can glue pull all except for AHSS and UHSS.

Aluminum Sheet Metal

HSS or High Strength Steel



Types of Glue

This topic can be very a very hot topic amongst PDR technicians doing GPR. All have a choice in glues used for certain types or damages, when temperatures and humidity play key roles. Our choice in glue has been Camauto Pro glue since it has been released. Used year round and in temps of 10 degrees Celsius below 0 and during the hottest and most humid during summers. Camauto glue pulls best at high temps and selection of glue gun will determine how well the pull will be.

Study Dent Damage

Taking the extra time to study the dent being pulled and panel affected. Strongest parts always first in order to relieve as much tension as possible. Then the less stronger like body lines etc. Last open areas and details. Remember No two dents are alike. Remember the first in part is responsible for all the other damages.

Image below shows that no two dents are considered alike. Although this is considered a great smash and not a dent. (C) Being point of impact and first in will be the last out. You want to pull the strongest area first in order to relieve as much tension as possible so (A) will be the first pull. Pulling forward with Camauto Pro Bar Tabs and relieving tension. And remember the first in part (C) is responsible for all the other damage. (B) and (C) have tabs placed below the bodyline and pulled (B) and then (C) at the same time creating more tension on (A) and as (A) (B) and (C) comes up (D) unfolds on it's own. Two hours of work with the right tools and tabs. Constant heat source and heat gel on the tabs to prevent glue failure.

Placing KECO 7 inch flexible centipede at (A) right above the line and double the glue used to help in preventing paint damages. Heated to 80 degrees Celsius prior to pulling. Two pulls and some blending. One hour setup time and glue pulling.
