This would keep the fender from flash rusting while I hammer/dolly out the dents.
I used the Picklex because it is supposed to prevent flash rust and allow me the time needed to bang out the dents. I am fairly sure it has phosphoric acid in it, but I need to review the MSDS sheet. Like you, I have small periods of time to work and need to keep the project moving. I will keep my website updated for those who want to see my results. I REALLY appreciate the advice given since I am new to all of the bodywork stuff.
