POR-15 vs. Caswell's Epoxy sealer
« on: July 10, 2009, 12:22:35 pm »
My Kreem sealer is degrading, crapping my carbs out and I'm going to reline it after I strip the Kreem sealer out. I would like to hear from folks that have used both or just one or the other. I was going to go with Caswell's but read a post on the Caswell's forum that made me worry and would love everyone's input, smart remarks or thread jacking  :)  ;)  :)

Always happy to threadjack. How 'bout them Red Sox?  ::)

Seriously though. Kreem sucks, don't know about Caswell's, but I've never heard anything bad about the POR-15 except that it's so damn permanent it'll be around long after your tank rusts out around it.

I used POR-15 on my tank but that was just a couple months ago so I don't have any kind of durability report.  In another post, I wondered if I should have just used toilet bowl cleaner and went right with the sealant.  You can buy the sealant alone for like $15.  I have another decent 350F tank, so I may try it ans see how it goes...

I went with the Caswell's after removing a failed Kreem liner.  I can only comment on the ease of use of the product at this point in time as the tank has only had fuel in it for a week or so.  I'm very happy with it thus far.

I am curious as to what post on the Caswell's forum has you worried.

edit: Thanks for the link...  Scratching head on that one though he does mention it was "brand new".  Harley tanks have had a liner applied at the factory for awhile now.  I wonder if he unknowingly applied the Caswell liner over another liner or thinking a new tank is nice and clean, didn't fully clean the tank.  A new tank has a thin layer of stuff on the inside that gets washed away with the first fuel up.

I've had a POR-15 kit in my tank for 2 years now... No complaints.

I can't find the post now because I can't remember how I worded the search, but a guy said that he followed the instruction and it sat empty for 3 months. When he finally used it the stuff was coming out of his gas tank and into the feul system. I know there are a lot of variable missing, but it makes me nervous all the same.

I've never tried POR or Caswell's but my Kreme job flaked like crazy.
I  did somrthing entirely different to  my VF700. I  used epoxy resin that you would use in fiberglass. It worked beuatifully till I totaled the bike 6 months later.
If anyone else tries this just remember EPOXY not polyesther resin. The polyesther will degrade after a few months, get all goopy, and do crappy things to your carbs.

Really, 2 years. No problems. No flaking. Nothing. Totally sealed, and the bottom of my tank may as well have been gone when I started on it. The steel that was left on my tank will rust away from the outside in before that liner gives... It's all about the prep you do to the metal. If you have doubts about the Caswell kit, then I think you oughta be decided here  ;) And once nice thing about the POR-15 liner is it leaves the inside of the tank looking like metal. Good luck.

my 72 350f came with that kreem crap in it. started to come off, and got me real good at taking the carb rack off of the bike. got another tank, used the por-15, no trouble after that. that was 4 years ago.

Many posts are missing vital information.
When people post about anything they need to give all of the details so it is useful information.

So if you are not interested in the subject ,no one gets to read about it?

POR 15 is a great product.  I've got an XL350 with a POR15 liner going on 3 years with no issues.  I always bake the tank for a long time to remove any moisture before applying the sealer.

and just to complain at posters who haven't been active for a year or two... typical  ::)

on a thread related note:  to anyone who may be considering their liner options, i used the Caswell this past fall and have had no problems.  It is thick, it is good, and you dont even have to be that thorough with your tank cleaning because it will coat over anything...even old failing liners.  You just need to be careful not to get it on the outside of your tank even if you think you have it all taped off and covered, cause that can bee a btich to get off...

Huh?... it's plain funny when 'Lucky' replies to a 2 or 3 year post and I mean a direct reply, not a comment,  directed to the OP as if they were listening 3 years later  ::) :o ;D.... plain weird ...... hehe !
