has anyone or does anyone ever use this shit ive had nothing but problems with this paint everytime i use it

first car was an astra estate doing it in mg blue it was a twat to cover for a matter of fact the car is still in bits in the corner, everytime i done the roof it would react thay kept telling me it was my problem but it was in a place that was emty no oil polish etc.

i bought some more paint of them for another car just done the roof and the same thing has happend i swear its there shit top coat the f**king roof needs re doing again you cant get a good flow on the paint the only way to do it is dust coats you cant put one good final coat on

i use to buy paint from another company and never ever had any problems with there paint it was expensive but i should keep to them
