[AMC-List] Baking Paint

[David Crooks <david.crooks@xxxxxxxxxxxx>]

<snip> places with ovens to bake-cure the paint in. they can't give it a 
really hard
bake unless you strip everything nonmetallic off, but even what they can 
do gives
you a better, more durable finish. <snip>

This is actually something I've meant to ask a real auto paint 
specialist...  Because I
don't believe that it's true of modern catalyzed  and epoxy finishes.   
These finishes cure
by cross linking into long molecule chains.  If the temperature is too 
high, they cure too
fast, resulting in shorter molecule chains and are weaker because of 
this.  If the temperature
is too low, then the reaction doesn't happen at all, and it never 
cures.  In any of the industrial
epoxies I've used, there is an optimum cure temperature range, for 
strongest results. 

What I don't know for modern paints is -what- that temperature range is....

I know some shops use ovens, not to produce a better job, but simply to 
speed up the
drying time, so they can shoot a couple of coats and get the car out in 
a hurry.

Cheers,

Dave
