this has prabably been covered somewhere but i have no clue. ok i bought some nason ful-poxy primer made by dupont recently and today i shot it on the sides of my bed..my question is that it seems real shiny. i always thought that primer was dull but ive never used epoxy before. i like it being shiny because i can see all my little dings and dents but i dont want there to be an adhesion problem. thank guy for any help

Well good job. When you spray on epoxy like that, having it be kinda shiny that means you didnt spray it too fast and have it be dry.... good technique. Those results are typical. Your concern about adhesion is a good question. You have to sand it before you recoat it. I know on some products they say you can recoat within a set amount of time, but after its dry i wouldnt trust the next coat to chemically bond, I like it to grip sand scratches, or mechanically bond. Other than that.... you should be well on your way. Anymore questions just post.

so what you saying is that before i spray my surfacer primer it would be a good idea to sand it?

The manufacturer's have some great tech sheets on their products. Ask you paint supply store or directly to the company. Some E-primers are NOT supposed to be sanded, and they just gum up the papers & make a mess. Find out the right way!

If anything is gumming up sanding paper, it isn't fully cured. If in doubt always go for the mechanical bond and sand it.
