Does Oven-Curing Spray Paint Work? (TIS350)

The Idahoan conducts an experiment to test the urban legend that baking a spray-painted part will harden the paint and make it as durable as a powder-coat finish.

[@DarkMatterX1]

In my experience a long, low process of curing spray paint at low temperatures (180 -220°F) for 4 to 6 hours does in fact provide a more durable coating. It's all dependent upon surface preparation. A uniform sanding layer to a 400 grit level, followed by a primer coat cured for 4 - 6 hours at the earlier temps. This step followed by 2 coats of color coat, each sprayed and cured separately in the same manner. This coating ends up being markedly more durable than an ordinary air cured rattlecan job. It's labor intensive, but it works. I've used it often for motorcycle parts, and they will withstand rock hits which would otherwise chip a standard paint coating.

[@onpsxmember]

How much does it safe compared to buying the powder if it's already labour intensive?

[@DarkMatterX1]

@@onpsxmember I just don't like the look of powder coat vs a good paint job with clear coat. If you find both finishes equally aesthetically pleasing, my way makes no sense.

[@onpsxmember]

@@DarkMatterX1 Usually I see powder coating with parts that'll see more abrasive wear or are positioned in a less visible place or to get a bit more texture for grip. I wouldn't use powdercoating for everything.

[@PSUQDPICHQIEIWC]

My results are similar, though I tend to ramp the temperature up after a few hours. I don't have a powder coating setup, so I'm not at all interested in any comparison. I consider oven-cured paint to be a technique to provide a fully-cured part without needing to wait a month for the finish to naturally achieve full chemical and abrasion resistance. ... but then again, most people don't even know that a finish takes more than a few hours to cure at room temperature.

[@shawnaburns5158]

I do tractor parts this way and the paint will not come off it's a great method

[@qhack]

The baking technique is based on the type of spray paint used. For enamel paints, you get the best result if you bake it. For lacquer based paints, there is no need to bake.

[@theARMORYchannel]

yup

[@Andi_Doci]

Temperature and time matter a lot. Paint is a polymer so too much heat and time could damage it. I would do minimal temp on the oven for no more than 15 minutes, then allow for the item to fully cool off with sufficient time thereafter. An error I can spot in this "experiment" is that the main reason for baking the regular spray paint is the curing speed vs not baking it. So the benefit of baking is that you get very quick curing vs waiting for 30 days. So, you should have done a test where you spray paint the piece then wait 30 days. Then on the test day you spray paint the next piece and then bake it, then compare.

[@TedSchoenling]

it depends.. In the winter I let my parts bake in a paint only part toaster oven for an hour or so. and that works better than leaving it out in room temp.. .but about as good as leaving the part in the sun on a hot summer day. IF You go to hot you will ripple the paint for sure and can even burn it and cause a fire.. so do be careful and never use an oven that you cook food in

Interesting, I always enjoy this type of video. Thank you.

[@bustinbass78]

I paint metal lures. Spray paint is not used because it just does not stand up. A couple casts in the rocks and spray paint chips off. Oven cured powder coat is my goto because it is so durable.

[@garycombs9435]

Oven curing is simply to cure the paint faster. That's why many car finishes are baked. It's mainly to speed the curing time.

[@stevest1300]

Oven baking is dangerous as hell. Even if she doesn't catch you during the baking, she'll smell it the next time she makes her crappy lasagna. You'll pay.

[@shawnaburns5158]

Not if you vinegar clean the oven out afterwards,,put vinegar in a pan run the oven and then clean it out thoroughly,,I do it constantly and no problem

[@summerforever6736]

man up!!

[@stoneyswolf]

Air drying can take weeks even months to fully cure 100% so all things being equal both fully cured there's no difference.

[@GregariousAntithesis]

Sand blast paint with rattle can enamel and bake at around 220 makes it tough as nails and way more chip resistant than powder coating.

[@johnbennett2855]

I think this is probably a carry over of baked vs air dried cerakote rather than regular spray paint

[@brassplyer]

Should have specified the temp and time of the baking.

[@harryjoe860]

Did you use appliance paint? That stuff works when you bake it

[@larryalexander4833]

Ceramic paint is more durable

My ak builds look great. Rustoleum appliance epoxy works great! I called that company and asked if they were eventually come out with more colors. Told me no🥺

[@harryjoe860]

@@250smacks good to know!

[@TronVila]

Rusto appliance epoxy is pretty incredible for a cheap spray paint. I’d bake parts at 170 for a few hours and it gets rock hard

[@Friedbrain11]

For some paints, it does work, but finding the right ones could be expensive.I don't think that it would eb as durable as a powder coating though.

[@TingTingalingy]

This is cool. I'm going to be baking my lower, this will be handy. Thanks!

[@ifell3]

Project farm would have made some sort of weighted jig aha. It just cures it quicker

[@maxheadspace2975]

Suggestion: HEAT the sample to 500 degrees before applying the ENAMAL spray paint.

[@liljohnp132]

I heat smallish parts with a propane torch before painting. Seems to help.

[@eabr2881]

I love your Superman curl. Lol, no offence intended. Thanks for the very informative video.

[@TheStigma]

What does "standard WD40 method" mean for powdercoating? Using the oil to make it stick instead of an electrostatic gun? Is there any video on that? It sounds interresting

[@ThePatriotParadox]

I had to re drill some trigger pin holes in my polymer lower, finally fixed them with JB weld, do you know of any any good hardening spray paint or such I can go over it with to ensure they don't woller back out?

[@IanThompson-sb8hh]

I was really only interested in the maximum safe bake temperature to use - the 1 thing that was missing from this video. So, not much use to me...

Why wouldn't you have used steel instead of aluminum?

[@rlbadger1698]

Thank you, good to know.

[@fuoman100]

Your testing methodology is not adequate to get an unbiased test. You are in yourself creating a false test by providing pressure on your own. From your video you even say you provided more pressure. A truer test would be to test all 3 samples under the same test in a way to remove your physical bias. Eg put the samples in a rock tumbler for a set length of time each or similar test to remove your inconsistency from the test. However good effort.

[@D56t37-cu7ol]

I used to paint cars. After the fresh paint sits in the sun for a few weeks the paint is much tougher. I think it's a combination of UV, infrared, and just plain heat.... I don't think heat alone can compete with the sun...

[@cowsongs]

The paint, even the enamels, used for painting cars is nothing like the spray enamel from a rattle can. I think most of your improvement came from the fact that the auto paint simply finished curing and hardening over a few weeks.

Very interesting experiment. :)
