Rattle can painting trick

I often rubberband the spray can with black paper (black sandpaper) and leave in the sun for a bit while I set up for the job. works great; solar powered. But I'm in San Diego. This method won't work for many of you for a few more months.

Look at the op. Take a hand held propane torch and set it half flame. Shake the paint can then hold the bottom of the can over the flame 10 seconds and then remove and shake well. Repeat 3 or 4 times until you can feel the paint inside start to get warm. SHAKE WELL. No danger of blowing up if you use a little sense. He didn't say "Blast it with a cutting torch until its red hot"

You are assuming total integrity of the paint can and a controlled amount of heat. Using a torch, or placing it for a variable amount of time in the sun, is just dangerous. Sure, you are smarter than the average bear, but why take a chance? You only need to be a little bit wrong once. If you can't realize the danger, by all means, go right ahead. But, methinks, I would not want you working anywhere around me. Safety first,eh?

Clearly idotis who just want us to use Rustoleum, right?:http://www.krylon.com/how-to/safety/spray-paint-safety-tips/
 
I just set mine on the porch railing in the sun for awhile, or in the winter bring them inside and set them on the heat register for the furnace. Seems to get warm enough.

Sometimes in the dead of winter, have the part and spraycans inside, hang the part on a wire, open the front door, spray it really quick then bring it back inside to dry in the warmth. No over spray inside and less fumes to smell.
 
Ain't no way I"m putting a flame on a pressurized can. Good Lord!
Sit it in the sun or under a lamp but no flame
Most famous last words.......
"Hey watch this"
 
I found if you paint "sections" it has best results on a car . by doing it in sections you avoid overspray ..............
 
This discussion reminds of an article I once read in a magazine devoted to the folks that into a frugal lifestyle. The author described a method of boosting the amperage of a weak battery in cold weather. He called it "bootstrapping" and claimed it had gotten his pickup started many times when he was stuck out in the woods in the winter. Basically, his method was to connect the two battery poles for 30-60 seconds or so which causes the battery plates to heat up and boost the amperage.

I was shocked that anybody would print this and have to wonder how many people were injured by exploding batteries. If you print it somebody will try it and they may not have the sense to know when too much heat is too much for safety's sake.
 
Milwaukee heat gun... gee spent 4 years using one removing 45 years of paint, one side per year on my 3 story home.. it worked very well....

OK. Heat guns are fun. But, we seem to be discussing applying paint not removing it, so exactly what is your point?
 
Christmas of '59 and aerosol can exploded in my parents home. From what I know it was set over the register to warm and just from that rise in temperature, it exploded. My sister suffered severe injuries.. She lost an eye, major facial cuts and many years of grueling dental reconstruction. To this day, scars are still visible and you don't just get a new eye.

Any one who suggests heating an aerosol can with a torch is stupid. Or worse.
 
I think I'll stick with heating my aerosol cans up under hot water. I know of someone who put a can into a pot of boiling water, the paint is still visible on their kitchen walls. The idea is to raise the can to around 35-40C, somewhere near 90-100F. Not much hotter than that and you can't hang onto the can to use it, so it becomes pointless going hotter.
 
I remember when they used Butane as the propellant in spray cans, it didn't take much to blow them up! Just set them on the space heater for a few moments too long and WOW! What a mess!
