Brush painting - what to use.

[Fastpedeller]

As it happens I'm trying to brush paint a car...... but it's polyester GRP, so more like a boat!
In the past I've had great results from single -pack paint, but I've tried to be too ambitious and used a 2-pack. Because there were a lot of brush marks I did a rub down and coated with some 2-pack varnish. I thought I'd really got a good idea, as it came out well on the front wings. When I had some remaining brush marks on other parts i decided to flat them and polish using a DA etc. The result isn't good, so I've decided the only way is to get a good finish off the brush, using single pack coach paint. It seems if I flat it all back to provide a key I can go on top of the 2-pack, and this will also provide a good colour base, preferable to a (probably) large colour difference undercoat.

Here's the question though......... Tekaloid or Craftmaster coach paint?

I've seen so many conflicting opinions, has someone (with experience of both) any experience?

Our fibreglass guy in work gets good results with a mini foam roller and single and two pack paint. Couple of coats and then wet sand and then polish. He also does the same with gel coat if a thin skin is needed.
