You shouldn't have any trouble painting those hatches. I have a Tempress hatch on my boat, and although it isn't painted, I am familiar with the look and feel of the product. I would test paint one hatch first. If you are satisfied with the results, then paint the other two in similar fashion. If you are not satisfied, then you only have one hatch to strip, not three. Make sure to clean the hatches thoroughly to remove any dust, dirt, grease, oil or fingerprints. Warm, soapy water should do the trick. Once completely dry, I would spray on the camo in light coats. When I do camo, I like to lay down a "base" of one color, and then add details with the other colors. If the paint you used on the boat isn't spray able, I would just pick up a couple of cans of H.S. Camo paint from your local Walmart or outdoor supplier. It is easy to apply, but you'll most likely have to touch up the hatches every few months if they see a lot of foot traffic. Good luck!
