Tank sealant
I need to order some stuff from Spruce, so Im considering ordering tank sealant in the same order. I do not see the tank sealant Van's has offered by Spruce, but Spruce has Pro Seal, some 3m products etc. Is Pro Seal or other products from Spruce good to use, or should I just order the sealant offered at Van's.

I've always bought the least expensive brand which was advertised as meeting the spec, and have never had a problem.
That said, there are some builders with a brand preference.

One thing to note is, last time I checked anyway, Van's sells sealant by the quart at about the same price Spruce carries the cheapest sealant by the pint. Something to consider.

Check delivery times from Skygeek. I bought some proseal from them a month ago. Showed XX units available. It took 2 weeks or so to ship. and another couple of days for delivery. I'd have had it in 1/2 the time from Van's, or 1/4 of the time from Spruce.

I personally won't use anything but PRC Desoto in fuel tanks.

Is it historic or familiarity since the PRC product was the first one generally available for RV tank construction?

non-tank ProSeal replacement
For places like in the snorkle around the top to make it air tight is there something besides ProSeal that works great? I'd use ProSeal but I need so little and the shelf life is so short it is expensive to use. What about high temp fire wall sealant like 3M-2000? Can I use it in snorkle around the aluminum parts near the top?
Same question for mounting stuff on or thru the firewall. Does firewall sealant act like an adhesive like ProSeal?
thanks

Fresh, in-date sealant is certainly the best way to go for sealing RV fuel tanks.
However, "pro-seal" remains a very aggressive adhesive for odd jobs for many years if stored in a refrigerator. I have leftover Pro-Seal (may be Flame Master) in the frig at the hangar that is nearly ten years old and I still use it as an adhesive with excellent results. Using the left-over quart kit has been much more convenient for various glue jobs than buying a new batch every time one of these tasks arise. I used it last summer to seal up some oil leaks on an old O-200 and that engine is practically leak free now.
