    Blow the surface with a heat gun. After a few seconds the glue will get soft and you can peel it easily. That is what I used with other brands. Never tried it with Porter Cable brand.

    Thanks for the detailed instructions, very helpful! I still have a few Bondo spreaders but with this super low viscosity resin I guess a brush is the easier way to go.

    Thanks for the tip! I have never used their products. Indeed a bit more expensive but I don't need that much, anyway.
