You're well away from any critical transition temperature for material behaviour changes. Ideally you would give it 24 hours indoors, but if you can be assured of material temperature higher than -5°C throughout, you're probably fine. </p>

Should I be worried about the sub being real cold-I am leaving a day early to get it out of the -17C that will be here. I imagine it will be near 0C in Burnaby- I have the chamber for a half day in the morning, but it will still be pretty cold I imagine.</div><div id="yui_3_16_0_1_1480288117059_3153" dir="ltr">Hank</div></div><p style="margin-top: 2.5em; margin-bottom: 1em; border-bottom: 1px solid #000"></p><pre class="k9mail"><hr /><br />Personal_Submersibles mailing list<br />Personal_Submersibles@psubs.org<br /><a
