Hey paint and body guys, have a look at this, and tell me what you think..... Options

This started as a paint bubble and grew to about 2" in diameter than it cracked and opened up.

It looks like the filler was spread over rust or the filler cracked at one point allowing moisture to creep under the filler. Because it's an outer skin and a large panel I would suggest stripping all the filler and paint off the panel and starting over. If the work over the top of the rust was done that poorly it's likely there is other work on that panel that will come back to haunt you..

The other reason for stripping off all the old work is a problem with the new filler blending into the old fill without causing bridging when the paint is applied. What is likely to take place is a swelling of the edge around the new filler that will be visible after painting. You end up with a bunch of islands and bannanas all over the panel. For the little extra time you will spend stripping the old work off it will be worth it.

Then any place that has that old pitted rust I would hit it with a spot blaster. Here's a link to the tool I'm refering to. There are some very affordable ones out there. Try Harbor Freight and other places if you don't already own one.

Use a good metal conditioner, Bump some of that old damage out before just trowling all that filler back on.... (IMG:style_emoticons/default/screwy.gif)

The rest is basic bodywork 101.
