Another method that gives very good results is to mount the board on a rotating platform while pouring/spraying the resist on. This gives a thin coating of resist, depending on the viscosity of the resist and how fast you are spinning it. An electric drill with variable speed works well here. -- Randy Steck Intel Corp. ...intelca!mipos3!omepd!mipon3!randys
