I have searched the threads but my question covers a finner point.
Pg 29-05, Step 4 says "Cover the heads of each rivet on the firewall with a thin layer of fuel tank sealant". The operative word is cover the "HEADS".
LP4-3''s - Does this mean just to cover the top of the head thereby filling the center of the pop rivet head? - or do I need to seal the periphery around the head also? Technically you would be correct to just "cover the top of the head".
Using a bright tungsten light I do not see any light coming through these rivets.
Keep in mind we are talking about vapor and liquid traces at low pressure where as the tank rivets are looking at up to 120 pounds of fuel pressure trying to seep around the rivets.
Any thoughts on making this a "neater" job. Saw one site where builder punched holes in pieces of masking tape to mask the rivet heads.
