I would use a foam fluxer since spraying rosin will make the stickiest nastiest mess you can imagine. 18 layer board huh? You will want convection preheat, both top and bottom preheaters, preheat tunnel of at least 4-5', a chip wave, laminar flow w

Hello Pete, I am not aware of any Wave solder machine manufacturer selling new pots from SS without being "LF compatible". Who would buy it now?? Also, machine warranties generally are no longer than 1 year anyway so all existing machines over 1 year
