Apply Spackle to Large Imperfections

one coat one coat of spackle is what we're gonna be doing i'm gonna trowel it on there those big holes and put a nice heavy coat of it on there so it actually fills them and we have something to sand now there is smaller holes on here that i don't want to fill with spackle and why is that spackle is a lot softer than bondo glazing putty so these type of small holes it'll be easy
