Primer seems like it should be straight forward and simple... but naturally things that seem simple quickly get complicated.
I'd like to use PPG DF50LF to prime my 71 challenger. I had the whole car media blasted, but as I removed the old floors and started preparing for new metal I've exposed areas that still have rust. After removing the rust and making my repairs; I'd like to prime the area to help prevent corrosion until the car is complete.
I've read that the DF50 gives you about a week to add high build / base coat to before you'll need to sand it and reapply. I'd like to avoid that if I can because it could be a year before all this body work is finished. Does anyone know if I'd be OK fore-going the additional primer or should I definitely do this?
What would those of you who are far more experienced than me suggest for the high build if that is what you recommend.
