My Pulsar XP wing tanks were resealed with Jeffco many-years back after r
emoving-the remanants of what was left over from the original sealer ship
ped with the Aero-Designs wing kit.- There has been no evidence of degr
adation of the Jeffco with the exception of the fuel filler-transition ar
ea from composite to aluminum filler ring.- That area was treated with th
e more flexible polysulfide close out plate sealer.- The specs for-Jeff
co are available on-line.- It is an industrial tank sealer that is rated
for even acid-exposure.=0ADave Weaver- N912GR-=0A =0A=0A_____________

Yes I have only used 100LL one time while on a long trip out to western Kan
sas from Illinois.- I use 87 Octane with up to 10% ethanol.- I currentl
y have 343 hours on 912UL Rotax engine.- At 5100 RPM cruise is 140 MPH an
d at 5500 RPM cruise-is 150 MPH (tricycle gear/large wheel option and 145
lb pilot).- Propeller is GSC-controllable pitch-hub with-Warp Driv
e blades.- The auto fuel burns very clean with no fouling of spark plugs
or carb malfunction.- As I mentioned earlier, where there is a transition
between dissimilar materials, I would coat that area with a polysulfide fu
el sealer and not count on Jeffco as it is brittle.- The polysulfide mate
rial can be applied over Jeffco.- Jeffco- can not be applied over a pol
ysulfide coating as it will crinkle and peal away.- It is a good idea to
periodically use an inspection mirror to inspect the areas-inside the-w
ing tank at the fuel filler ring and-the aluminum vent tube for hair line
cracks
(if Jeffco is primary sealer in use).=0ARegards - Dave=0A =0A=0A__________
