VHT Epoxy Paint -- an unexpected discovery

[duffeycycles]

I like to spray paint when the parts & paint are warm & a little cure with a light touch with air heat gun helps bake it on.

Interesting read! I always put my rattle can painted parts on a stand over the wood stove (winter months). The paint gets soft and levels out while hot and then hardens as it cools. Summertime isn’t so easy.

My glory days of scrounging are long gone, Chuck,...

Local alleys and bins dried up badly in 2008, and never fully recovered; The recent panic is the second decimation.

There is occasionally useful modern stuff, but quality goods of the last century are extinct.

Fortunately, I have righteously hoarded piles for years that I haven't sorted. I don't even know what I've got.

Cotten -- it looks like you and I are dumpster diving at the same places . . . I often find a lot of my favorite "tools" behind businesses and scattered at second hand stores.

I can't wait to try some parkerized burgers, Chuck! Thanks for the tip

The trick is to use a big old stainless steel warming tray. They are dirt cheap from Amazon at roughly $18 -- or you can dumpster dive behind catering and food service places. They toss out dozens of these trays. I use the 18" versions which hold just over two gallons/8 liters of solution and are long enough to do axles, etc.

I have a grill with four burners and then the side burner. I put a bucket of boiling water on the side burner to preheat and degrease parts -- then right into the park solution. No contact with the grill itself. nice part is that the most dangerous chemical is the phosphoric acid; which is pretty low grade in park solutions. I wouldn't drink the maganese solution . . .but doing some stuff outside is not much of an issue.

Here's a photo from when I was doing it indoors on hot plates -- but same concept.

Toaster oven warning, Folks!

Got a large one in the paint pit for cylinders and cases, etc. Or what's left of it.

A partner ignored shop procedure of warming rattlecans in a Nalgene beaker of hot water at the adjacent sink.
I ran down the steps into the dark after the big bang, to find him picking glass out of his face. And he left a big chunk o' hair in the garbage can.

I hate paint.

The challenge with bbq grills is controlling the temperature. They often get too hot for all but exhaust paints.

I prefer to use the grill for parkerizing.

It sorta all comes down to what you are comfortable with and what your experiments yield.

I was thinking of putting in a piece of sheet metal over the grill grate to diffuse the heat more evenly. My grill has a thermometer and I also have one of those laser temperature gauges that I can use to check the temp. I may try this and see if I can control the temperature this way.

Don't forget toaster ovens and heat lamps, Folks!

(Especially when it comes to removing botched paint.)

I like the convenience of kerosene, GitGuy!

Thinking maybe rather than use the oven in the kitchen, why not set the parts in a gas grill outdoors?

Also, rather than use a torch on exhaust components has anyone try to "cure" the paint with a heat gun?

Has anyone tried these techniques?

I wonder if oven curing makes the finish fuel resistant.

It improves resistance, of course, Larry!

But that doesn't mean it will be fuel-proof in the ever-changing and infinite variety of fuels, and combinations thereof.

Even powdercoating proved that.

Sneaking parts into the oven...I learned that was a recipe for an explosion. I learned that the first year I was married.

In addition to this tip, I'll offer another that is not exactly the same, but in the same vein.

I learned a while back that when painting exhausts with hi-temp paint I could combine dry and cure times by torching the paint.

I've dinged soft paint when installing exhausts that were not cured. I've also ridden bikes that stank for a long time if the pipes weren't very hot. (Looking at you, two-stroke junk.) Further, if a set of pipes is long enough, the back end may never really get hot enough to cure in a reasonable time frame.

Enter the torch. You can spray and heat almost immediately. Paint cures very evenly, and then you also get rid of the stink in one shot, and you can put up an exhaust with glass-hard paint, reducing the possibility of unsightly nicks.

Has worked wonders for me over the years; maybe it will help one of you other guys.

VHT epoxy black paint is one of the better rattle can paints I have used for gloss finish.
