3M™ Polyester Thinner is used to help thin body fillers to help reduce spreader drag, which can adversely affect the final results.

Achieve Better Filler Consistency
For best results with fillers in auto body repair, it's sometimes advisable to thin the filler with 3M Polyester Thinner. Body shop technicians commonly use thinner to get a smoother consistency, which reduces the occurrence of pinholes. Thinner may also be necessary when you need to spread a very thin coating of filler. This thinner is easy to use. Simply add a small amount of thinner and mix thoroughly. Keep adding until you achieve the result you desire. You should still use a normal amount of hardener with the filler. 

Restore Rather than Toss Old Filler
Thinner may also be used to restore "dry" body fillers. Similar to other applications, mix in thinner in small amounts until you get the consistency you want. Being able to thin drier body filler helps you reduce waste of shop supplies.

3M specializes in developing new ways that science improves the performance of professionals in a range of industries including collision repair. 3M™ Polyester Thinner is a great example – a product that makes fillers easier to work with a smoother consistency.
