Is this the PPG fuel tank coating? If so: http://www.ppgaerospace.com/Products/Sealants/Specialty-Products/PR-1005-L-Buna-N-Slosh-Coating.aspxAll I can find is a "dry time" of 20 minutes. Just curious if anyone knows how long it needs to cure fully. Is 20 minutes all it takes?
Having dealt with many types of sealants, etc., I would want a "typical performance" and let it cure for 2 days. Some products I've used had 72 hour cure requirements. But if you're in a rush, a quick call to their tech support should clear things up.But I'm not sure.
