I used a chrome spraypaint to change my robots colour, the one I used is normally used on cars.(I put a primer on first)
I did a really good job, let them dry and stored the bits in a box individually wrapped in plastic to protect them.
I unwrapped them today to put some decals on and the paint is all scratched on certain parts, I rubbed it with my finger nail and it scratches easily... what have I done wrong?
Gutted, now I'm gonna have to remove all the paint and start again right now my motivation has been destroyed, not looking forward to removing that paint!

Look at what you have as a nice base for the real top coat
Leave it be. In fact when my bot is done I'm gonna dry brush it to look weathered/battle damaged.
But if you really want it pristine, get some 0000 steelwool, scrub it down, lay another coat.
to protect it, get some Castin' Craft Resin Spray.
Do not mess with crappy clear coats, they are finicky and may not be compatible with the chrome basecoat and may wrinkle your precious paint job. Resin spray dries in a few minutes, dries hard and crystal clear (applied properly of course), is chemical resistant, and wont care what the base coat is, as long as its dry. Plus it's cheap.
With it being my first build I would like him to look fresh and clean cut lol...
I will be rubbing him down and reapplying a fresh coat, not sure whether to use a more durable spray to finish him off yet or use a clear spray or a clear resin spray as a final coating yet, although the resin spray seems hard to find here in the UK.
But at least it doesn't seem as bad as it was earlier when I first discovered the scratches
will keep this thread updated and open until I've decided.
The most important step when spraying anything is for the surface to be rough so the paint has something to stick to. I haven't started painting Melvin yet but when I do the process will be this;
1. Clean all parts avoiding any silicone based cleaners (silicone is your enemy, the paint will not stick to it at all).
2. Rough sand all parts.
3. Apply plastic primer.
4. Apply 2 to 3 coats of paint.
5. Wet sand.
It's pretty much the same way I've done any car repair. While it may be painting plastic rather than metal the basics are the same and the paint is the same. It will need that rough surface to bind to, it will probably need the wet sanding to remove any runs and blemishes and give that high quality finish.
A wet sand followed by another coat (or 2) should fix any problems. The sanding will remove any loose paint and key the areas that need the paint to bind to them, the next coat should cover the bad spots and a final coat followed by a very fine wet sand should even out the paint, remove runs, blemishes etc.
If you are interested, the torso itself was painted with Rustolium Textured Metallic over automotive primer.
Gotcha! Thats why I recommended resin spray. I do it a lot, I build custom guitars and I make metallic finishes that way...chrome base, transparent paint on top, then resin clearcoat. The clear is not exactly paint, but polyester resin thats thinned enough to spray. It dries like a shell, so crappy basecoats are somewhat forgiven. It also fills in imperfections.

PS. Your link didn't work. I would like to check it out.
You need to include the http:// in the url
Best suggestion would be to try out Rustoleum Hammered Metal. I used it on all my costume pieces to make it look like metal. It has a awesome texture ans is a rugged scratch resistant finish.
And thanks @Rich for the step by step instructions you gave earlier and all the other advice you've given me.
@Danger, I ordered some rustoleum clear paint already so I will be careful and only do a small area first to see if it reacts with the chrome.
I'm gonna rub it down so it's nice n ruff and then respray the original chrome spray and then a layer of the clear paint. It's the cheapest option at the minute seeing as I already have a few tins left, If that fails I'll take the advice @Doombot gave and try the resin spray.
Nice guitars by the way Doombot, would love that job lol I used to repair musical instruments so can appreciate the work thats put into them
@Danger just copy the link and paste it to your browser bar. By the way I like the retro looking light fittings on your robot
@jstarne1 I may try that paint if all else fails with the chrome I have Thanks for the help and advice.
Castin' Craft Resin Spray
I promise you I DO NOT work for them hahaha
I only do the guitars on the side, my main job is in the oil industry. I'm a Senior Electronics Tech. I'm a frustrated F/X guy haha. I know a few pro F/X people in Hollywood and I'm pretty knowledgeable about materials/sculpting/electrical/animatronics. Long story short this is how I stumbled upon EZ-b. It's an awesome little board.
I really can't wait to show everyone what I'm working on.
Good luck with that paint job now!
