<div class="h5"><br><br> Bob et al,<br><br> <br><br> What's the standard wall thickness<br> on the K-boat VBT? Is it approved procedure to weld<br> extra material at the [water valve/drain plug] site before<br> threading it? If so, it seems it would be possible to<br>
have the insert flush with the interior wall. At least<br> it wouldn't project where it could interfere with<br> draining of the tank and would make it easier to<br> flush.<br><br> <br><br> Thanks,<br><br> Jim<br><br>

<br><br> This has given me an idea. Ive got loads of this<br> fluid film stuff. Im tempted to pour some into the<br> tank to give it a bit of protection over the winter. <br> Might have to experiment with it a bit first to make sure<br>

if instead of an FRP tank you could modify an AL-80 or<br> AL-100 scuba tank to perform the same function.<br> Unfortunately they are not large volume and would not<br> produce a lot of buoyancy.<br><br><br><br><br> Jon<br>
