Apart from the manufacture of Plexeal resin-bonded gaskets, the Haddenham Engineering Co., Ltd., of Haddenham, Bucks (Tel.: 218) are introducing Lacalex lacquer and solvent which, they claim, enables paintwork and cellulose to be protected from the damaging stains left when methanol or other alcohol fuels are spilt. The lacquer is clear and does not change the colour of the paintwork over which it is applied, while it can be removed by liberal application of the solvent. The lacquer costs 75s. a gallon and the solvent 27s. 6d. a gallon, and smaller quantities are supplied.
