alright so i just finished my interior with base coat clear coat.  i ran out of clear and missed some spots,   i heard that once you apply clear and it hardens that you cannot add more clear is this true.  i was told that it will peal off.  the clear has been on for 5 days, so is it to late to hit it again with another coat of clear?
 
you can add as much clear as you want...i put 10 coats on my interior...wasn't satisfied so about a week later i put 10more.
 
 
 
wat he said ^^^, or u can wet sand it a little with 1000, and then put a @!#$ load on it again.

I put about 5/6 on mine and it came out flawless.  Whoever told you that you couldn't, should be hit in the head with a tach hammer cause they are a retard,
 
yah, well the body shop that sold me the clear said the it has to be applied  when the paint is tacky.   he said that if i wait till the paint fully dries the clear wont last,  down the road it will peal off.
 
if it is exterior base/clear, then sometimes flash coats are required for proper bonding.  that is correct.  on interior applications though, if it is from a spray can, you should be fine.
