35:12 how much you sand? I never understood this. Many people show that they sand and sand and sand. But how much? what should i see or feel on surface? It must be silk smooth or smooth without any sanding scratches?
Finish out to a 220 grit go to the other side of the car and see feel and look it will show you what you need then use the guide coat to help you when it's gone you should be on the right track just make sure there's no pinholes if there's not prime and your done.
If you have the guide coat still showing your still to high if the guide coat is gone around the area and there's some left in the center it's low meaning the low needs more filler,the scratches depends on what you grit the primer says on the TDS if it says 220 then prime if it says 320 prime it's really not rocket science my friend.
