Question Duracoated Mini 14

So I am planning on Duracoating an older Mini 14...I understand that the barrel gets pretty hot after a few mags...so my question is....has anybody duracoated one and had any problems with the finish after the barrel heats up?

Not at all, but it will wear just like any other "Applied finish". Still looks good.

no problem, I did both my mini 14 and 30 5 years ago. I just recently resprayed the bolts on the 14 from simple wear. Never had a problem with any other part, barrel, slide, etc.

I also have question on that. What exactly is the duracoat and is it hard to apply. Can someone with average skills do it, or is it best left to a good gunsmith ?

DuraCoat is easy enough for the home applicator now that they have released the Shake and Spray kits. It won't be a "pro" job unless you have access to blast cabinets and proper air supplies, but it works well enough. The most important thing is preparation. Fail on any of the surface prep and your results will suffer. The parts need to be disassembled, totally degreased and then prepped by scuffing or blasting. If any oils are left anywhere they will leach into the coating. Wear powder free gloves after degreasing as finger oils can contaminate the substrate as well.

I've been doing DuraCoat for a little over 10 years and I've only had one come back that was ruined from heat. DuraCoat has a high temp formula, but it isn't as durable in regards to scuffs and scratches so I would just stick to the regular formula. I've had mixed results with the SL or self lubricating formula, mainly uniformity of finish.

Prep your items, apply as directed and let it sit overnight before handling or adding a second color. It takes a few weeks for the coating to reach its maximum cure and durability. Also be very mindful of the humidity. As we come into Spring and Summer high humidity will cause issues from blushing to outright non-curing. This is an issue Lauer Weaponry confirms but there isn't a fix for. If it's really humid try running an air conditioner and desiccant filters in your air supply, or wait for a better day. A cheap hygrometer will tell you what the conditions are better than the news.

At the current pricing of the shake and spray you can afford to experiment a few times before you get too heavily invested in coatings. A pro job is always best because we have the equipment, experience, and most of us will offer at least a limited warranty on the finish, but it's not cheap and home jobs can be very rewarding.

Another product that works well from home is Brownells Alumahyde. Spay can convenience and it's pretty durable. Other than that you start getting into the thermoset or bake on finishes which are difficult to work with for first timers and the smell coming from the oven will get the married user into trouble...fast. Remember that with any "baking" product that you can't just lay it on the rack and cook it or the rack will leave lines in the finish. You need to use wire to suspend the parts from the bottom of the rack. Pros who do thermosets like CeraKote and GunKote generally have dedicated $2000+ ovens for vertical hanging.

So try it. It's not hard it just takes attention to the small details to get a good job and letting it sufficiently cure before hard use.

Well, since you've claimed to have enough disposable income to buy minis two at at time and smash one of them on a tree...

then you have enough money to have John duracoat your rifle for you.

it is worth the money, and the time it takes to send it to him.

you won't be disappointed. I certainly wasn't - he did two of mine

get a trigger job while it's there (if you haven't already) the stock trigger feel is gritty crap - it'll be "butta" after he's done with it.

Got pics? Is durakote as good ad this cerakote I am now reading about?

I would like to have my 9 mil hand gun re-finished at some point. Not happy with the factory whatever it was.

It's been my experience that CeraKote is a good product in the thermoset formula. I offer it for some things where DuraCoat isn't the best choice. For your slide I would use either, but if you use a Kydex holster without any moleskin I would opt for the CeraKote. I find the air cure CeraKote isn't as resistant to scratching as the heat cured.

Each will claim to be the best and have their devout proclaiming their virtues, I like to choose the finish based on the use since each has it's own pros and cons. GunKote is the grand-daddy of all of them and is still a good choice for plenty of applications.

I recently Duracoated a Mossy 500

Naturally the pattern I chose (British DPM pattern), was the "lets get the more complicated pattern to start coating with" moment. Do not get the duracoat dvd, it was worthless. I learned more and worked up my nerve to begin by watching guys on you tube, imagine that! This firearm is my dedicated sabot deer killer gun so I won't be firing it till this summer- fall and will not be subjected to rapid fire heating. The satin gloss overcoat really makes it a professional looking job. It was kinda rattle can looking before the satin was applied. Not sure about heat but I know they offer a few different products and you would think there is a formula or process to make it hold up to heat. But now that I have started working at Brimstone they bought the oven for doing Cerakote and I gotta say it turns out awesome. All my future coating projects will be done with this product. And it has a great reputation for durability.
