I was laying up some BID on some foam for the VStab parts. I layed up the one side and then went back to the HStab. Several days later as I was waiting for some curing on the HStab I went back to the one sided glassed foam to lay up the other side. Because of the way I had stored it there was a significant curve in it. I layed up the BID on the other side and then I put some duct tape on some boards and then placed some heavy water bottles on the boards to let it cure flat. The next day when I took off the water bottles and boards I had a surface that was smooth as glass. So I was wondering if it would make sense to apply a similar technique elsewhere. I am about ready to apply the final layup of fiberglass on the HStab. Should I lay down some peel ply and then vacuum bag the whole thing? I went to a little local fly in and they had some composite planes and my son-in-law asked if my surface was going to be that smooth. I told him I thought so, but I didn't know how it would get that way. Is that smooth final surface achieved with primer and sanding alone?
