Yes Dawn works best I am told so that's what I use.
Now that I look at the truck in the day light. It is not as good a job as I thought. Not too bad but I will have to sand and recoat. I did polish a little and it came out ok. I am just concerned that there is not enough paint there. I will sand with 400 or 600 and recoat then work the finish.
Then I can get back to the bed.
