I have read a few treads on the Joey mod and i saw that a few people who used Krylon fusion paint were having issues with the paint blistering after a while. Seems like some areas get very hot around the ballast...

So since i am looking for a satin/flat black finish, would a good BBQ paint do the trick? It is definetely one of the most high temp resistant paints out there. Any opinions on this??

Thanks

 

I used it on a part of mine when it was black and it worked great! It's not as black as you might think, but that's not necessarily bad.

 

some people had blistering with just the paint... others had the actual plastic blister with the paint

 

Am i right to assume that most people who do the Joey mod use Krylon Fusion paint and have no issue even after a long time of use?

 

i used krylon fusion with a primer and some sanding with steel wool...

i have blistering of (just?) paint on one side and not the other... i guess it depends on how well you layer

 

Mmmm, i was all ready to start doing the mod but i am kinda slowing down now... I dont feel like touching up the paint or whatever once it's done. I guess I'll push my researches farther before staring it.

 

my $0.02 here...

blistering paint is usually due to the improper application. not that the type of paint has NOTHING to do with it. but you can use a relatively low quality paint, and still make it stick.

blistering has a number of reasons... like painting on hot surfaces.
people may sometimes wash the surface with warm water, or paint outside on a sunny day... bad idea.
painting on a hot surface can cause the first layer of paint to create a bit of vapor (just because its evaporating). then when the second layer goes on, it may trap some of that vapor under there. we're talking very tiny amounts here, not very visible, which is why most people don't notice it. then everything dries, you put it back together, then sometime later after all the heating up and cooling off the vapor does, it blisters.

another reason is painting on wet surfaces, and not letting the surface fully dry. same thing happens as trapping vapor under there. sanding makes it even more complicated. unless you get a nice even sand, you risk creating microscopic grooves that hold moisture when it comes time to paint. don't need to tell you how that turns out.

what i've come to have as a "safe" method for painting...
use cool water to wash things, not cold, but cool. towels and paper towels do not get ALL the moisture, no matter what the bounty commercials say. i use a compressed air can, the kind you use on a computer, to get the tiny bits of moisture off after drying it with a towel. you can use a hair dryer, but that creates a hot surface, and then you have to let it cool off before you paint.
all in all, you're looking for a clean, dry, surface thats room temperature.
After painting, let the part dry in a garage or somewhere where the sunlight isn't beaming down on it.

once you're done painting, it should look smooth, much like it did before it was painted. if you've ever seen a paint job that looked like the paint had "texture" to it, thats what you don't want. (unless they used actual textured paint that is)

 

Thanks DarthGoon, those are actually great tips... Especially when talking about paint that will be exposed to unusual conditions (ie much heat).

 

Great write up DarthGoon - I can now take better steps to make sure my Joey is a one time only job. Thanks!

BTW, good idea with the BBQ paint! Wouldn't high temp engine or exhaust enamel work well too? Good for temps to 1500 degrees on some cans.

 

theres a company called Alvin (i think... i just remember the can is white).
they make "automotive paint" particularly for painting surfaces with volatile temperatures.

the dude who introduced me to it had used it to paint his brake calipers. at the time, he had had them painted for like a year, and they still looked perfect. i have no idea exactly how hot it gets down there, but when i was younger i once touched a brake rotor after someone had just parked their car and it flash cooked my finger tip. i figure if a paint can take that kind of heat on a daily basis... then i'm sold.
