POR15 experts,

I have stored my car for the winter, in my garage, in the Northeast. POR15 directions say to apply in temperatures over 50 degrees. I have pulled off the door strips, found a little rust, and dried the area. I plan to wait until April for the POR15 treatment (in warmer weather). Should I spray something on the seams from now until I treat, or just apply the POR now? Thanks.
