I'm, about to start the dreaded fuel tank build. The VANS Accessories Catalogue talks about Quart packs of sealer. LAS only do 150mil packs. Another RV9 builder tells me he only used about 300 mil for his, but to check in case his memory is like mine! Apart from the mess, what experience please.
Thanks

Hi  Robin  
 
A few tips on proseal and tank building  
 
•      Don’t skimp of sealer more is better
•      Mix 1OO grams at a time; the working time works out about right using this amount.
•      Ensure the proseal  is  mixed well  
•      Keeping proseal warm helps you work with it  
•      Cover both parts with pro seal that  you are riveting together  
•      Once riveted, cover over the shop head of the rivet with a dab of sealer.  
•      Have plenty of latex gloves / rags and MEK or thinners to clean up with  
•      Don’t try to do too much in one session.
•      Try to ensure you leave a bead of sealer around the parts that have been riveted together this helps to ensure a good seal.  Very important on the rear tank baffle.
 
A lot of builders report that they don’t like this part of the project. To me it was a very satisfying part of the build. Proseal gets everywhere if you work in say 45 minute sessions followed by a clean up this will help you in the long run.
