randydanger Posted April 6 Report Posted April 6 what is the best sealer to use for 1) closing up the access panels and 2) spot sealing or brushing over what look to be trouble areas in the fuel cell? it actually looks very good with the exception of a few areas. it appears a brush on top coat after cleaning would/should do the trick. any suggestions as to materials best suited and positive outcome??
N201MKTurbo Posted April 6 Report Posted April 6 The sealers called out in the maintenance manual work well. The manual also gives the procedure for cleaning and prepping the metal for any tank sealant repair. Besides, the methods and materials called out in the maintenance manual are the only approved repair methods. 2
Fritz1 Posted April 6 Report Posted April 6 as stated the service manual has all the info, if memory serves me right CS3204 is used for the access panels and the screw in the wingwalk, this is as far as I have taken it, everything beyond that is best done by somebody who reseals tanks for a living, to my best knowledge there are 3 companies that strip and reseal tanks, weep no more, wet wingologist and a company in Houston, there are quite a few shops that are perfectly capable of patching a tank, however if the sealant is more than 20 years old strip and reseals typically is the only procedure that produces a reliable result, typically 7 year warranty after strip and reseal 1
