KR> Sealant

[Jeff Scott]

I have not used Proseal on glass or Rotomolded plastics.  But the description 
of the application sounds like he's trying to seal under a washer of some sort 
on a tank fitting.  Proseal should work well for that.  Proseal stays flexible, 
which you need for a plastic tank.  If you had a weepy glass tank, my 
recommendation would be different.  I have one of those I'll be repairing on 
the Cub this spring.

By the description, this sounds like a rotomolded Polyethylene tank.  I would 
not attempt to use a glass resin, including vinylester, to seal polyethylene.

No Dan they are not fiberglass, some kind of poly that has been roto molded I 
think?  most like other ultralight tanks?  I will investigate the Pro-seal to 
see the specs?.  as you guys have used it successfully I have no doubts?.  I 
will attempt to obtain the specs on the tanks and then return? Thanks of the 
response all of you? jw

Jeff,



Have you used Proseal on fiberglass tanks?  I was going to suggest that, but 
did not know how well it worked with Plastic or fiberglass.

Joe,



By plastic, do you mean fiberglass?  The fittings in the fiberglass tank in the 
KR are secured in place with a flox resin mixture.  Use Vinyl Ester resin and 
you should never have a problem with it.

I have a need to find a suitable sealant to put around the fittings that are 
installed in plastic ?? fuel tanks.  there is a aluminum fitting that is held 
in the tank wall or base with a large washer and nut

KR Group, First of all Happy New Year to all. 

 I?m in the process of building a different airplane, but have followed this 
site for a long time.  Way too much good info to stay away.  I have a need to 
find a suitable sealant to put around the fittings that are installed in 
plastic ?? fuel tanks.  there is a aluminum fitting that is held in the tank 
wall or base with a large washer and nut, also a small rubber o-ring that is 
squeezed between the washer and the tank .  Seems a bit fragile to me and 
wondering if I can?t strenthen the seal with a semi-liquid sealant that would 
stand up to the fuel?  I can?t find a caulking or sealant that is resistant to 
fuel?  any ideas? tnx  jw

"Gorilla snot" is what we called 3M weather-strip adhesive and no it is no good 
for sealing anything with heat applied.  It is good for holding gaskets in 
place until assembled.  The best stuff for making liquid gaskets is GM black 
RTV that is O2 sensor safe gasket adhesive and maker.  This one works stand 
alone is designed for all automotive applications, and is gas and oil 
resistant.  The 3M will eventually get hard crack and leak.  The Permatex will 
not.  15 years of auto repairs proved that one for me working in the 
profession.  It has also become the standard from the assembly line on 
virtually all rear wheel drive axle cases, valve covers not using rubber 
gaskets, the ends of the intake gaskets on V6 & V8 engines, and much more.  
Good building
