I plan on detailing my wife DD this month.. the exterior is in good shape just some minor swirls but between her and my 3yr old the interior is a mess...Since I can only do the car on weekends is it bad to stretch it out over two weekends...My plan is one day just do interior then the next day I would wash, iron x, clay, pretty much get it totally prepped then the next weekend start by giving it another wash then proceed with the polishing, waxing and all the other stuff...Is this ok to do or am I better off trying to get it all done in one weekend
