Layed up both sides of the F28 bulkhead using the "pre-preg" technique, 2 plys BID. Worked great, peel plyed both sides. Layed up backside of F22, tow plys of BID. Peel plyed edges. Attached router template to instrument panel with carpet tape to trim edges. Unfortunately peel ply got caught up under trim bit bearing and knocked the template loose. This messed up the edge. I decided to repair by cutting the upper corner of the IP off and splicing in a new section of foam. Bummer
