chalky plastic panels

Adam....... The previous post was spot on for these panels......

I've had some so bad that the edges were flaking.......They need to be cleaned up and "edged" (if they're that bad) with a bit of sandpaper, and the surface smoothed as well from the chalky texture.....gotta be careful not to go too far.

After that, the new Krylon "Fusion" can be applied in 3 separate coats to refinish and strengthen the remaining plastic. It has binders and flex additives that really do a good job on the plastic.

I've used it with great results.
