You mean the mistakes I made when I first used it

Come a long way since then thankfully!

I enjoyed your video.

no different in terms of durability to any other 'normal' spray paints ive used..

if you want durable.. get a local powder coating firm to do it and save yourself all the horrendously time consuming prep work..

Don't powdercoat road bikes that have soldered lugs.
You'll be driving a gummi frame. It'll be ruined.

Thanks for the feedback.
I'll go with Montana then.
I need to paint a frame.
Do you recommend;
Montana primer,
Montana Gold
and any 2k clear coat?
I don't know much about bike paints but I've seen on YouTube its better to use a 2k clear coat

E-Tech Engineering Ultra Zinc Primer

E-Tech's Ultra-Zinc Primer is a long-lasting, rust preventing surface coating for ferrous metals. Once applied properly it creates a waterproof barrier to keep rust and corrosion out.Easy to applyCan be overpaintedFast dryingE-Tech's Ultra Zinc Primer is a zinc-based surface coating. It uses...

Primer I use. It gives anodic protection against corrosion so even if you chip or scratch right through to bare metal it should still be protected.

I don’t use 2k for a couple reasons, it only takes a fraction of a can to do a frame and 2k has to be used there and then so it’d be a lot of waste and also it’s very carcinogenic so you really want a proper, air fed mask if you’re using that kind of stuff.

The numbers for the melting point of silver silver and the baking temp for powdercoat can be similar*…but only if letter that follows those numbers is not.

* And even they’re not even that close. Silver solder melts at 650-750deg Celcius, powder bakes at max 400deg Fahrenheit which is around 200deg in Celsius.

But still, don’t powdercoat nice steel frames for the reasons I mentioned in my earlier post.

I read somewhere you aren't supposed to use 2K over acrylic. Is that true?

As long as the acrylic has completely flashed off it should be fine. They can and do react occasionally when still flashing though. You take your chance and hope really.
