If you want to go satin on the brunswick green then ASK your local Painter and decorator if he has any MATTING AGENT then you can add some a bit at a time...trial and error on this one to matt the paint....you could also ask in your local paint stockist and I don't meant B&Q Wicks etc a proper paint shop
The only other alternative left to you is to ask in B&Q for them to mix a ltr up of satin paint and hand paint your decks with it.... they have a rather large choice of shades of it on their paint swatches...
Carl, YES it is the carrier and thinner inside the aerosols
