Hey folks!

Got a bit of a graze on my rear quarter and am looking to blow it in, ive done lots of spraying before and can always get good finishes on new panels but never had to really do anything like this before....

Just wondering what techniques people use as im a little confused, tried to do it once and could only get a dull area where the laquer had misted around the surronding panels and my attempts to buff it up were a little bit unsuccessful, ended up respraying the whole side of the car which tbh i dont feel inclined to do!!!

Any help would be much appreciated!
