I’m one of the old timers who was just used to cellulose paint. I am painting my classic car now with 2K paint. I plan on using base coat and clear lacquer. My problem is I am painting two colours (black and ivory), I have been told that if I paint the black base coat first I have to paint a coat of clear lacquer within 30 minutes of painting the black base so it will bond to the black base coat. Once lacquered and dry if I mask the black off and paint the ivory base this will react with the clear coat at the edges of the black. Even if I mask right to he edge of the black then mask to the edge of the ivory, either way fresh paint will have to touch whether it be overlapping or edge to edge.
As I will only get one chance to paint this I am trying to reduce any problems or reactions.

Do you have any advice that will help me paint the car? How would you tackle the job and what products if any would I need to buy to achieve it if needed?
Thanking you in advance
Cheers Mark
Thank you for your response Wolf but I am using base and lacquer for a reason. The vehicle is a working wedding car and I want it to shine. I also don’t want the paint to wear through like the cellulose has on edges with constant waxing and polishing. I just neet to know if it will react and blister and if there is a way of avoiding this. Many thanks
