- one panel at a time, i dont know - those that can spot this stuf will see that in a nanosecond esp. at sunrise and sunset, or in parking lot light - easy. esp silver, just how the body panels were and teh way the paint flakes fell can be spotted....

as far as cost and price i did a motorcycle last weekend -two of my friends and i - $1200 for teh job - that included supplies, time, surfacing, ect...and a custom ghost pearl flame job - we are 23 year old rookies - the guy was thrilled a nd quoted up to 3k for the "same work"
-just throwing ideas/opinions

if you are going to do - one panel at a time - pick a major body line and go up from there...depending on the condition of the paint the old paint may be able to be brightened back to a high luster - close to new by the same shop.

so hard to say without seeing it.
