In paintless dent removal, there are two methods of pulling a dent out, one is a glue pull and the other is using suction. It’s important you learn how dent pullers work before you even think about PDR glue.
What is PDR Glue
When using a glue pulling kit you’ll be given tabs that are made to connect your dent puller to the panel using glue.
Paintless dent removal glue is made specifically for pulling dents out of panels. Because of this, it’s stronger, more flexible and is easy to remove from metal without leaving any marks behind.
Most glue sticks are made to a universal size that will fit any quality glue gun.
Which PDR Glue to use?
There are many cheap pulling kits out there that come with their own glue.
Most of the time this is a very cheap glue that isn’t going to get you very far. You may find success with the glue provided in the kits but if you’re looking to go pro and do some serious work, you’ll be better off looking elsewhere.
The main factor that will determine which glue to use is the temperature. Colors don’t really mean anything, however, a lot of brands will use colors to indicate what kind of temperature they should be used in. Just pay attention to the tech specs and you’ll be alright.
AnsonPDR has compiled a list of the most popular glue sticks and which temperature they should be used in.
Depending on where you’re located, you’ll likely get away with owning 1 or 2 sets of glue sticks. If you’re a business it’s probably best you have one for each type of weather, just for peace of mind.
I personally enjoy using Hawg glue but if you were to choose another brand from the list above you wouldn’t have any issues. As you learn your trade and experiment with different brands you’ll start having your own preferences.
How to remove glue
There are 2 methods of removing pdr glue.
The most efficient method uses isopropyl alcohol or acetone.
Have a bottle filled with isopropyl alcohol or acetone that you can either spray or rub onto a panel using a cloth. Make sure you’re wearing gloves when applying it otherwise your skin could become agitated.
Once you’ve wet the glue and surrounding areas with either isopropyl or acetone, the glue should peel right off. If it doesn’t, wash the chemicals off, let the panel dry and read the second method listed below.
The second, least efficient method is using heat.
When removing glue from the car after a pull, you don’t want it to be hot. If you attempt to take the glue off while it’s still hot you’ll just spread it around the panel creating a bigger mess.
Instead, make sure it’s warm enough to be flexible. Grab your heat gun, set it on a low speed and heat that sucker up.
Once the glue is heated up it should peel off easy enough. Sometimes this method will require a putty knife and a steady hand. It’s far riskier and is more time-consuming and should only be used if isopropyl and acetone do not work.
Always make sure that there is no residue left behind. Why would you remove an ugly dent only for glue etching to be left behind?
Again, acetone or isopropyl will remove any residue, make sure to work fast to remove the chemical from the panel and make sure you use a clean rag, the last thing you want to do is scratch a customers vehicle.
PDR Glue not sticking? What can I do?
Every dent is different and there are many different factors to consider if your glue is not sticking to the car.
First off, you want to make sure you have high-quality glue. As previously mentioned, a lot of the glue supplied in cheap kits is not good enough. Choose a reputable PDR glue.
Secondly, have you remembered to wash the panel you’re working on? Dirt will decrease the effectiveness of your glue
Thirdly, have you made sure that the tab you’re pulling with is clean? I like to clean them with my glue remover (Isopropyl or Acetone) after every job, that way I won’t have any delays on the job.
Finally, is your glue hot enough? Not heating your glue gun up to the right temperature before you try and apply it to the tab will affect how much it sticks. It’s also another reason why it’s important to have the right glue for the right temperatures!
Where to buy PDR Glue Sticks
Unfortunately, the world’s best retailer (Amazon) only supplies a small handful of PDR glue sticks.
You may be able to pick up some glue sticks at your local parts & motor stores but as far as online retailers go, I would suggest using: Dentrix, AnsonPDR or PDROutlet.
All of the stores mentioned above ship worldwide but currently, the Dentrix store is closed.
Buy Cheap, Buy Twice
Or worse, buy cheap and have to buy the more expensive product anyway.
When doing PDR it’s important you set yourself up for success, cutting corners on quality is only going to come back and bite you, especially if you’re selling services.
DO YOURSELF A FAVOUR AND BUY QUALITY.
