I got recomended to used coach paint for repainting my 90 but havent heard of it before anyone have any feedback on if its a good idea or not?
I've been using it since the 70's. Yes it's good stuff, but you have to apply it in the right conditions if you want the best results, otherwise you will have brush marks showing everywhere. Do it right, and it's hard to tell the differance between it, and a respray to the untrained eye.
The most important thing is don't apply it in direct sunlight, this is because it drys so quick, that the brush marks in the heat wont get chance to disapear like they should before it dries. Don't do it on a windy day if doing it outside, or you will get all sorts of dust etc sticking to it.
Don't apply it in damp conditions either, or it will not take, and always finish painting a panel once you start. if you do say half a door, then go back to it, you will see where you have been.
So, the best thing to do is apply it in your garage (if you have one) if not, just make sure it's not damp, or windy at all the day you do it if doing it outside, and make sure it's overcast.
Ideal conditions, is in a warmish garage, with just a blow heater going to take the dampness out of the air, and use a good quality soft brush, if you use a cheap one, you risk hairs coming out on your paint work. A nice soft 'harris' brush is best. Do one panel at a time, and take your time, don't be tempted to work it in too much, a little goes a long way. 1 ltr should do a whole short wheelbase landy if doing outside only.
Some people use gloss rollers to apply it, But I think you'll get better results with a brush, a roller will show slight stippling.
