Gaming cloth upgrade ~ Early steps

It's been a while since I last posted. The reasons are many and varied, but basically Life got in the way. So, now things are a bit more settled, here's my latest project. 

Last year I bought this section of green cloth from the local ReStore/Habitat For Humanity shop for a few dollars. It's seen a couple of games since, but I've wanted to get rid of the totally unrealistic uniform colour for a while. 

I'm not going to follow the mastic/silicone caulk approach used by others. A little experiment shows it'll take poster/craft paint well, so I'm going to do a small area at a time and see how it goes.

Putting the Table back in A J's Wargames table

So, with the exception of one more piece of hardware, the table's finished. I need another hook and eye combo to ensure the folding legs don't collapse while it's in use. It's one of those cases where I could've sworn I had two of the things but no...

The casters work a treat, but now I've got everything back together after our move, I can see how stained the surface is in places. It's a souvenir of water spilling from the plants we had over-wintering on the table at our previous house. I also miscalculated where the screws holding the leg mountings would go, which required a few touches of plastic wood to fill in the holes I drilled. The result's not pretty, so I'm thinking of applying a good coat of blue paint to the surface to hide the marks and make the table suitable for naval gaming, but I'm unsure how the paint would affect the particle board. Will it or won't it warp, in spite of the battening below? Inquiring minds would like to know...
