Yes I know the first thing you thought when you read the title was "Idiot" but no I am not planning on doing one, it's just a curiosity as I've just finished the base coat on a pair of front & rear valances for my dads car in metallic black.
What's to stop someone from doing a decent job with cans? I have looked into it but all I can find is stuff on forums where people have sprayed a car matt or satin or not even prepped/finished it properly.
What's to stop me from getting a decent can finish? I have done quite a few repairs using the stuff and apart from a pair of cans that I think were contaminated (mixed to order not off the shelf) which developed fish eyes I haven't had much problem getting a decent finish with some hard work flatting it back & then polishing the hell out of it.
The hardest bit is blending in as cans never match factory that well but this would be irrelevant on a whole shell.
I have painted the entire engine bay on a car two years ago and that still looks fine although admittedly the car hasn't moved yet as it still isn't finished and I've also done several repairs on my Mondeo which are fine still after 3 years.
Here is a door repair I did after some twonk was careless in a car park 3 years ago, this thing was the size of a 5p-

After, there are some ripples as you see but it was done from start to finish in a single weekend, had to buff it out a 2nd time a few weeks later again once the paint hardened but it's been fine since-

Again, a quick temporary wheel arch bodge repair to get rid of a scab done in less than a day, even had a downpour 30 minutes after the clearcoat went on-


Is the issue durability/resistance to UV, or just most people don't have the time or inclination to do it properly?
I see no end of cars with replacement wings & bumpers still in primer or painted really patchy, not polished out, paint peeling off, run mark galore.
What gives?
