I have let the rust encapsulator dry/cure yesterday and today. When the cowl vent repair kit arrives I will prep/clean the areas and use rust encapsulator to seal/cover the affected areas.
I purchased a seam sealer, Dynatron Seam Sealer 550. I will use that to seal the various foot panel and floor panel seams, driver and passenger side.
After all of that is done I will need to apply an undercoating especially in those areas under the car.
