Hi , As you are aware , I , am building the LCS-2 . This was and is an opportunity to test out the MR.COLOR primer surfacer . First the ship , this is important too ! When and if you choose to buy and build any of these ships they may be twisted slightly . I know this can be a pain , and thats why I chose to let you know. The P.E. is good and the kit does contain clear bridge windows! Imagine in 1/350, window glazing !! Now as to th MR.COLOR . I bought the 500 grit of this stuff . This is some beautiful stuff . I was able to ffill small gaps sucessfully using it brushed on , It filled the small gaps very well . Very litte trouble brushing it either . More later . tankerbuilder
