What are Thinners?
Thinners are, as the name suggests, used to thin down certain paints and clean up after using them.
What Kind of Thinner do I Need?
If you're unsure about what thinner to use, it's best to refer to the instructions or datasheet for the paint/coating you are using.
In some cases, a specific thinner will be offered to go with the paint. This is particularly the case where the paint is more technical.
