If I spray clear over flat paint, will it appear glossy when finished or will it look like flat color under glass?

Depends. Did you get glossy or matte clear coat?

Gloss nitrocellulose...I plan to spray about 12 coats and then wet sand to 2000 grit, then run a graduated series of polishing compounds

Also, should I wet sand the color coat, or can I just dry sand it up to 800 grit?
How fine do I need to go on the color?

I'm not an expert by any means, but I believe you'll want to wet sand the color coat.

I was thinking the same, just not looking forward to it.
Will probably just go up to 1000...get it flat and remove any lines.

I think it depends on the type of paint. I'm no painter, but I played one for a few days to save money I got from the insurance check. I did not sand the color coat, I don't think you're supposed to with some automotive paints.

What are you painting and what type of base coat? I'm sure real painters will be around shortly to give you a real answer.

Working with aerosols to paint a guitar body.
A detailed thread is posted in the musicians forum.
Hit a snag with a plan to use stain and I'm now looking at paint.

+1. Wet sand with 1000 until you see no shine. Dry then clearcoat.

Put a couple of drops of the color in the clearcoat and give it a millky look. Makes it look better.

I did a guitar years ago with automotive paint. Actually used fiberglass resin first with ultra light glass cloth. Then primed and painted it like a fiberglass car part.
But if your base and clear is comparable, no need to sand before clear coat.

you do not typically sand the base before you clear. you can if you have a minor piece of trash in it, but then you should put another coat or two of base on. if you dont you will probably have a discoloration where you sanded, it may be blotchy, or you will see the sand scratches. if you just want to make it super slick, wat sand the color with 1500 then spray a quick coat or two of color to even up the color, the clear it.

Can you buy it in cans like spray paint?

I have a suit of steel armor that I want to protect.

Yes, that's what I am doing. Don't do this often enough to invest in real spraying equipment. Just going with aerosol cans.

Don't sand the basecoat unless there is an imperfection. If you do you will most likely have to apply more base.

No need to sand the color coat. Some aersol clears do not wet sand and buff well. I painted a guitar for a guy a few years back, came out real nice. What color is the base coat?

Planning black right now, but that could change.

Anyone know if it works on bare steel? How does it hold up?

bare steel, or aluminum for that matter, must be etch primed before any paint is applied.

I sand my base coats with wet 1500 grit to take off the orange peel and again after I clearcoat. I only use dupli- color automotive paint and my only experience is raw steel with etching primer ( I wet sand that too).

The airstream trailer folks used to sell the clear they would put on the trailers ( bare aluminum ) it's known to hold up well, you probably can't get it anymore because of the EPA, I'm sure a search on coatings for airstreams would come up with the latest stuff.

The best spray can paint comes as two part paint in a single spray can. You break a seal and the two parts get mixed internal to the can. Sprays like normal paint but the paint itself is MUCH better.

It will shine it up a little even if you use flat clear coat. I do that with a lot of AK's I get in. Hit with Rustolem flat black and go over it with Rustoleum flat clear.

The clear coat makes the finish much tougher.

Yes it will, you need a flattening agent in the clear.

To get proper adhesion it needs to have chemical and mechanical adhesion. Scuff, etch primer,block it smooth, fill primer, block it smooth then paint. Do that and it will hold up like a car. Inside it would probably hold up for a long time even without clear.

I work in wood. What happened to your stain plan?
