Coating a Fiberglass Tank with POR-15 Clear

Yes, and they stress not using anything else. Mike

I just coated 5 tanks using one quart of POR-15 Clear without using any thinner since using a full quart allowed for enough material to roll around in the tanks without being thinned, and the results were very good. I have been purchasing it directly from their website to assure it is fresh. Mike

How many coats per tank?

Thanks,

Scott,
Like stated in the first post, "repeat the whole process again 2-3 more times, and when finished let the tank set open for a couple of days and it will be ready for use."
3 coats is generally sufficient, and leaves an obviously glossy finish on the inside of the tank, but occasionally an excepionally dried out or porous tank may not be quite as glossy inside when finished. I have found that POR-15 Clear is best applied in shop temperatures of 60-75 degrees. Mike

Whats used to clean the semi hard oil goop in the bottom of tanks?  (fiberglass)

[SouthRider]

I use the slow but steady method...

Soak the tank in a 5 gallon bucket filled with hot water, spic n span, and mineral spirits. You can also add simple green if you like.

It will ooze slime from the tank for a couple weeks until it's done.

I change the mixture periodically depending how bad the tank is.

Works like a charm, and so far I haven't had to coat my tanks (but I never use gas with ethanol).

Southrider, not sure I agree with you alltogether, Mike's attempts, come from yrs. of experience, and he is usually on top his game. I have used Por15 externally/topically in conjunction with epoxy primer, have also seen very poor results with Kreen and other so called internal coatings. I will defer, and in the spirit of things, our attempts are not to make claims of being an expert. So it seems reasonable that we/I/you should wait. Chemicaly (typo) would it not make sense, to clean the internals, which are conductive of POR 15.

Commendations to Mr.Winter!

I would think if any cleaner is Completely Flushed out it would be fine. The goop I have is pretty thick.

Thanks Tom,
I think that the point made here is if you plan on coating a tank with POR-15 Clear, that any built up residue should be removed, and it has been recommended by POR-15 representatives that Lacquer thinner should not be used, as it leaves traces of oil behind which can caused adhesion problems. Instead they recommend the use of POR-15 Marine Clean, which is a water based cleaner and let the tank sit a day to dry or use forced air to speed drying prior to coating the tank. Mike
