Many add a small angle to the rear wing base.. If you do a blow over that wing gets all the damage. The angle wil help hold it in place from future blow overs--- looking good. All the elbow grease comes In soon. I like to use a light weight fiberglass & resin from your local hobby shop. Why do I say that, all the moving the hull when done in and out of the car ,house --you add resin down lay glass over the resin use a credit card to remove excess resin. It doesn't go around a 90° corner. It will lay over curves remove excess glass and resin when dry. Then move on to another area. Do the bottom first it's the easiest so you get a feel how to apply The West resin or automotive resin works well. Many don't fiberglass due to the weight gain.
