I have seen alot of disscussion regarding putting clear coat over primer on the Internet. I am looking for a cheap, darkish red colour for my rod project and I think red oxide will look good, but can I clear coat over it? I hear primers alone are not good becuase they don't have the protection which a top coat will give them, and clear coat will make it a little glossier, and also protect it from UV light. Am I right? I know very little about painting cars so this might be a dumb question.

Or, you can use polyurethane satin paint - brush, roller or spray. Cheap and easy to use. Looks reasonable too (sold as military vehicle paint) available in the full range or RAL and BS colour codes (google it, I cant be bothered right now )
Matt paint is generally quite porous, so moisture can get in and get to the metal easily which equals rust so either paint it onto a gloss undercoat or clearcoat is the only way to prevent water ingress.
I've been told by several people that matting agent in gloss paint don't give the effect you'd expect. Based on this advice I stayed away from it when I painted my car.
You can clear coat on top of primer, a friend of mine who works at a body shop has a mk1 golf which he painted in grey primer then laquered over it (he put glitter in the laquer) but IMO it looks good.
From personal experience I painted my Sierra matt nato green with rollers (which gave an alright finish), then later sprayed it with a compressor and gun (which looks much better!). I used acrylic based paint from Cobbaton Combat......
Same here, thinned at least 50%. Used KP04 thinners for synth enamel, celly'd probs be OK but it's a bit fiercer. You can get 'nice' celly and gunwash celly, price difference isn't much at all. But hey it's only primer ...
I have used clear over primer before. Worked well for me. It was only done to prevent the repairs from rusting through before the car was painted properly as primer is porous. It gave an interesting effect I quite liked.
Proper red oxide comes in matt or shiny, ( shiny = not high gloss!! ) Yes it can be sprayed, just add thinners to taste matt or shiny is water proof as long as the coverage is good.. It will take a while to harden though
Get it from a steel building company as they use the good stuff as opposed to halfords etc who I reckon use water with a red tint!!
most paints can be matted down, you can getting a product called Matting Agent, the more you add the matter the paint, better getting the supplier to do it for you as they know how much to put in, some high gloss paints need loads...
