spraying

I am going to purchase some duratec surfacing primer to use in my bilge and transom area. When you coat the area with gelcoat do you have to use their high gloss additive as well as a wax sanding additive or do you only use one or the other so that you canpolish the finish? thanks

If anyone has the time to waste to look at this long video of the pin heads getting pepper sprayed at the END of the video, enljoy. To sumarize, usual sit down protest, some arrested with tents and kept on ground. Main large group at one point walks over to arrestees being held by PD nearby...

Im doing all of the work my self. I am not going to have it sprayed. Recommendations on painting to get the best wet look Roll and tip?? Brush with fine badger hair? Penetrol/adatives? Any and all advise will be much appreciated.
