I had some spider cracks on my paint yesterday on my 56. I touched the cracked area and paint broke off. I had no option but to grind the old bondo which was cracked and redo it. My paint job is 3 years old and in nice shape. Anyway to fix this? Should I have a body shop do this and can they blend the paint or do I need the whole hood painted. Any estimate on what this will cost to fix. Anyone in Southern CA want to make some $$ LOL... Any advice will be grateful. Thanks everyone.
Here's a pic:

 

A good painter can tell you if a reasonable blend can be done.

The problem is that this may just be the proverbial tip of the iceberg.

 

If you have bodywork that's already cracking, chances are the rest of it will as well, judging by the truck, it's black, I'd highly advise against a blend, you'll never really be happy with it.
