I really like this Liner Xtreem cause it covers a lot of bad body work on this 54 yr old trailer but I'm not sure you can paint over it so I used Dove grey Raptor liner for the body.my take on this so far because I never used it before is: It's very nice to work with, a 3 part mixture if you add the color additive but not near as thick as the xtreem,my only complaint about it is,although they leave enough room in the quart container for the activator there isn't enough room for the color addititve so I had to mix it in a different container an all you do is shake this product,plus since I had to cut the tube on my spray gun for the extreme,the raptor you can screw the gun on it an its a taller container so I had to buy another gun for it but that was only about $15.
