Last layer of fiberglass is on the tank
I have been sanding down the bumps every two layers ( i now have six ) to avoid getting a major problem in the end , seems to work quite well , before the last layer the tank felt reasonably smooth , so i don't think i will need very much bondo , fingers crossed .
The petcock bunge is in place , i used the old one witch i cut out , sanded down the metal left around the pipe , drilled some holes in it and sandwiched it in between some layers of fiberglass .
On the first pic the filler neck is in for a test fit , it is approx 3,5cm high , and approx 1 cm will be visible over the tankbody .
in the lower 2.5 cm i cut some grooves with an angle grinder to increase ( at least in my mind ) the bond to the epoxy , then i put it upside down in a hole i cut for it in some styrofoam ,with the bottom part protruding and made a collar with fiberglass , it will be something like 1,5 cm wide , and tomorrow i will fuse it to the tank with epoxy .
And BTW sanding fiberglass is some itchy sh..
