Re-coating black CG blades

Hi all,

have taken off much of the black color on my blades, after abusing them for some time.

Are there any products / paints out there which I could use to touch up the worn-off patches, and prevent rust seeping through ?

I don't want to send it to a custom shop for a refurb, I need my knives daily.

The final result doesn't need to look great, just functional (ie a tough coat, able to withstand abuse, and prevent rust underneath).

Am looking for a matte black 'crinkle' finish for current combat-grade Busses', but plain matte black is also fine.

Thanks !

Peter
 
I personally would just strip the entire blade. Rust is not too much of an issue as long as you dry off the blade if it gets wet. I stripped my FBM and used it most of the winter in the forest... I had no issues with rust. Plus it looks a lot cooler when there is none of that nasty coationg covering up the raw infi ..
 
+1 on the stripper... I stripped my SAR5 (below) because I really prefer a non-coated blade. It is not necessary to remove the micarta handles when stripping, I was going to polish it up but decided against it.

If you want to keep it crinkle then look in an auto store that has a healthy selection of engine/valve cover paint. There is a black crinkle coat paint that looks very similar to the busse coat. It's very durable as far as air drying paints go but takes a few weeks to cure to full hardness at room temperature. I'd just strip it, or not worry about it. Rust is not an issue on infi, while on the coated models there's often a layer of rustable decarb (paper thin) the infi beneath is pretty rustproof. Any rust you see is just cosmetic and will come off with a little scrubbing. The decarb soaks up oil well, if you keep it oiled even the decarb won't have problems. I've tryed making it rust faster in hopes of getting the decarb off easier, it's worked but still alot of elbow grease to get into the corrugations.
 
I tried to do a bit of research on what decarb is and as far as I can find out it is Decarburization (usually unintentional), the loss of carbon from the surface of a tool steel as a result of heating at a high temperature in a medium or atmosphere that reacts with carbon. i.e. after heat treating. Hopefully someone can confirm if this is right.

Yoda - Will paint stripper remove the decarb?

In terms of rust proofing, is it actually better to strip the coating?
(assuming the decarb is removed in the same paint stripping process)

Sorry pd999 if this is a bit off track from your original question but I think the answers to these questions may be related to your rust prevention on infi theme.
 
Thanks, all those ideas look good.

Will definitely try the car paint 'crinkle-finish' trick.
 
I never reall thought about painting a Busse but this thread gave me a few ideas aloreay.

Maybe I'll recoat my Shelly warden.. Engine block paint or brake caliper ceramic paint may do the trick...

Here is my FFBM all wet and no rust after this day in the woods..

DURA COAT!

Great stuff. I've used it and like it alot. Good strong coating and you can put it on as thick or thin as you want.
 
I know it sounds funny but what about Rhinoliner? That stuff would probably be a good coating material for a blade. Or some kind of spray on bed liner material.
 
Someone else suggested a Rustoleum Hammered finish, presumably using something like Hammertone), though its not really a 'crinkly finish '. Hopefully won't adversely effect any exposed INFI.

Noticed on the Crusader Forge Knives website (http://www.crusaderforge.com/CUSTOMFINISHESCF.htm) that they use Gun-Kote (similar to Dura-Coat?), which seems to work well on their knife steel.

Wonder why a 'crinkly finish' is used rather than 'matte'; maybe to reduce reflections even further? But doesn't it affect cutting ability over a plain matte finish?

Paint stripper won't touch decarb. You can remove it via abrasive, and it's quite wear resistant. I've tried soaking in acid (wheel cleaner or vinegar) to try to remove it chemically, it seems to soften it up a bit but I still had to use sandpaper and scotchbrite to remove it.
