Re: rear lights mk1
It seems that you havnt prepared the surface correctly, athough your method is correct. Many people have this problem for some reason, and i think it might come down to the type of polish that is used on the car. 1200 will take it off yes, but after that id clean it with thinners, not methys as methys stays on most things, so that could also be a problem if you used that to clean it before hand with the soap also. Also, id applythe coats within 20 minutes of each other, as by then the surface has dried enough to accept another coat, then leave when you are happy with how dark it is. I did mine with 4 coats, getting progresivly heavier with each coat (by a very slight amount) as each time there is more decent foundation to coat onto (i you know what i mean). As some paints dont like to adhere to the same surface when its completely dry
