As the purchases I was considering, such as a vaccum dust extractor and an air filter (for decoration purposes - chemically stripping old paint from some wood to varnish it, or sanding other wood as a key for repainting, and repairing and smoothing plaster on walls prior to repapering-), were quite expensive, I wanted to be sure that what I bought would be suitable, so I phoned Toolpost, and was able to speak to Peter, who was very hepful and knowledgeable in his advice and guidance in my choice of products to meet my requirements. And if he couldn't speak to me at the times I called, he did ring back. Old school service. marvellous. Thanks Peter. Regards, Roy.
