Caulk for tail light bezel

[TowAir]

I can't find this in a search; I'm sure it's been asked before. I recently repaired my tail lights, and I need to know what my options are for caulk. I put putty where there was putty, now I need to finish the job. I know about Acryl R, but I want to know if there are other options that might be easier to obtain and apply. Thanks for your help!

Tempro makes the best. Go to Vintage Trailer supply on the web and you can find what you are looking for I think the number is Tempro 635. It's grey/silver, drys soft and stays that way for years. While you are doing the lights I caulk the bottom rub rail top and bottom to prevent water getting in there.
