Frustrated with inability to do body work!

W&G remover is not a real solvent....so to speak. It will exaporate...just like any other liquid material. Too be honest, I never thought about the elapsed time on the W&G remover on the surface since I just use it for wiping down.....generally. It does not take much water. Try a gallon of distilled water as it should be mineral free and it will go a long way. Softened water will have a certain degree of "hardness" remaining even after going through the softener.....or so I have been told. As well, softened water has an amount of salt content....which you, certainly do not want. Yes, prior to your next coat of surfacer, sealer, BC paint, or clear, you would wipe it down with W&G remover, but you want to NOT introduce any contaminants to you project's surface....if you can help it. Enough can go wrong anyway. Clean, and keep clean before your next coat. BTW Rod, I sent a PM to you regarding some parts. Thanks. Old Dart 66
