fixing bubbles on quarters

i have a few paint bubbles on my rear quarters that has been eating at me for awhile now, rest of car is good,they are not all the way through, what is steps to fix these on my own? thanks

The best way to kill rust is to cut away and replace any soft parts and sandblast all the pits in the remaining metal clean. Once you get that done clean the area with a metal treatment and then spray epoxy primer on it to seal it. You can put a thin coat of filler over the epoxy to hide any pitting.

So you don't end up doing it twice take a small mirror and a flashlight and look down between the trunk extension and quarter panel to determine if the rust is starting from the inside and working it's way out. This will give you a better idea of what, if anything, is hiding under the rest of the paint. Lots of times there is more rust on the verge of poking through and you may fix one small spot and eventually the rest of the stuff you missed will start poking through later on.

thanks,never thought of mirror i cant get my hand in there to check nor my wifes either, seems to be only surface bubbles,like a bad prep job or something, rest of car is in very good shape, i bought 2 years ago and i know they did a repaint not long before that, also they havent gotten any bigger in 2 years, any tips if they are only surface bubbles? thanks

Take the paint off with a 3M paint stripping disc and a drill. Sandpaper is too slow and paintstripper is messy. You will need to feather the edges in once you get around to putting paint back on.

thanks
