POR'ing Frame - Topcoat too?

[BroncoDad]

Getting ready to put POR15 on the frame and was just wondering - I know that it is UV sensitive and will discolor if exposed to the sunlight - but is that in direct sunlight or just being out in the daylight? How much will it affect the frame being under the body? Is it just better to do the topcoat and be done with it and not worry? Thanks,

Yeah, top coat it while you can after it's slightly tacky. Not a big job, just one more step.
I know it's not in direct sunlight, but indirect light will discolor it also.
