Definitely got to steer clear of the E10 stuff and I've seen the 98 Caltex take off 2 pack paint like paint stripper. Haven't had an problems with the 98 in my Bultaco Pursang tank as yet.

Hi Barry,...I have used a product called "Slosh" on my Bultaco tanks and up to now no problems.

about to do mine with Caswell

Here's a trap for young players the petrol cap entry has a lip that goes into the tank below the level of the fibreglass so to drain the epoxy out i have had to drain it through the petcocks
-
Problem with having to drain through the petcock holes is the actual size of the holes. As the resin dries it starts to solidify over the small holes, so you have to keep putting the old petcock in and out and then use a small screwdriver to remove the cap that starts to form. I'll finish off when set with a drill just to ensure new petcocks will operate

I've had no problem with storing 98 premix in my 1960s and 70s OSSA, Montesa and Bultaco fibreglass tanks and have only lined some of them with epoxy because the inside looked weathered or had glass strands showing. I've also got a pommy fibreglass tank made in about 1980 that is still going fine and has had 98 premix sitting in it for about 2 years now.
Would not be game to leave anything sitting with ethanol in it though

Who was the idiot who plugged the breather hole with bamboo, Oh right me. Other than having to drill that out it all appears to have bonmded so fingers crossed

took me ages to "drill" out the curved transferr pipes on a explorer tank i sealed with caswells, (only one tap!), flattened welding wire tip,shoved it in a drill & worried it for about an hour,finally burrowed through,whoopee job done,lesson learnt, :P
