SS Metallic

So, many years ago (a lot) I shot SS metallic by applying a single relatively heavy wet coat and done. Reading a lot on the forums I notice most are doing multiple coats of SS and sanding between coats - at least for non-metallic. If nothing has gone wrong, why the multiple coats? Is it because a single coat cannot be applied thick enough for durability?
Does this process apply to metallic as well? Particular paint I plan on using contains a very fine flake. Guess I'm looking for a modern day primer to shoot a SS metallic - is this the right forum for that?
 
Single stage is clear with color added. So you are talking about one coat of clear which is a bad idea. I spray a fair amount single stage and it’s usually four coats. I don’t sand between coats.

I’ll also caution you against single stage metallics. You can’t cut and buff them. What you spray is what you have…

I'm shooting a '56 Panel with rather large surfaces so I think perhaps the BC/CC will be a better way to go. I already shot the firewall in SS - will it be a mis-match with the rest of vehicle in BC/CC? Can I sand the SS and shoot BC on it?

How much time between coats? Just enough time for the solvents to flash off, unless some sanding is needed?

30 minutes depending on temperature. Never rush it and risk trapping solvents.

There really should be no need for sanding base, not sure where this is coming from. If you have a nib just lightly remove the nib with an 800 sanding sponge. Don’t go crazy sanding your base. It’s a bad idea imho.

If it’s just one coat it should be redone anyway.

Right, I didn't mean the whole thing, just an imperfection(s).
 
Anytime I hear someone mention single stage metallic I picture a disaster. I see absolutely no benefit. I know people that try thinking they’re saving time and money. Guess what, they ended up spending more time and money cause they ended up redoing it in bc/cc.
 
actually boats which are painted metallic are all clear coated ss. ss is always used for durability. there are metallics in the awlgrip and awl craft line as well as alexseal and axalta's marine/transportation line. they are all clear over ss. same goes for other high abuse vehicles like dump trucks and tractor trailers etc. they are always ss. real bitch to get the metallics right.
 
So next step would be to determine coverage rules of thumb to know how much paint to order - are there any? Do the paint manufacturers have info on this?
 
A very rough rule of thumb is 8 ounces per panel per coat. Will depend on mixing ratios since that rule is for ready to spray.

Always order more than you think you need to allow for mistakes and resprays. Especially with metallics.

Cheap base is not cheaper because it will take more coats to cover. Try to use a decent quality base.

Ok, so what do you think of this calc - for a '56 Chevy Panel Truck - figure 3 gal total mixed BC?

That is probably in the ballpark. Those trucks can eat a lot of paint. Are you painting the firewall, inner fenders, inside of doors, dash, inside of cab etc?
