I'm planning to use POR-15 to rust-proof some of the metal on my frame, and maybe even the steel outer skins. I'd also like to use Sika Flex 252 (the adhesive) and 226 (the sealant) in various places.
Anyone else tried the two together successfully?
Neither vendor knows about the other's product.
Thanks,
John |

I've used both, but never together. The only thing I've found to get POR-15 off is a side grinder! Unless there is some chemical reaction between the two, I'd guess that probably wouldn't be a problem.
A word of advice, after opening the POR-15, it has a short shelf life. Therefore, I like to buy it in the six-pack halfpints. Anything left over in an opened can, I throw away afterwards. On a bigger job, it may be more cost effective in the quart. |

I have used POR15 with extremely good results. Wear gloves when you use it, if you get it on your skin, you will wear it for a few days till it finally wears off. It definately STOPS rust. It cures to an extremely hard surface and it seals the metal and stops the rust.
It is really runny until it starts to cure, can be sanded but it is a hard paint like nothing you have ever seen and it sticks hard. what ever it is on, it isnt gonna come off easily.
I used it on metal on my bus and it protects from rust just as it says it will.
I have heard of SikaFlex letting loose and panels falling off the bus. You have to use the cleaner and primer, all costly and then the sikaflex. All these have a very short life after the container is opened. It also is date stamped as the product has a short shelf life also, YOU MUST USE FRESH PRODUCT!!
I have heard of other bus guys using a product from the Home Depot that was cheaper and easier to use and not so fussy about shelf life.
Others here will also give their experiences with this sealant for you to make your learned decision. Thanks for asking - cd |

I had some Sikaflex 252 left over and used it as a caulking compound. It let go of anything I put it on except bare steel that had been primed with their primer/cartelist. That is holding great.

Which adhesive from Home Depot is being used. Thought about using Sikaflex to glus steel panels onto our bus (reskin) but not too sure now. Don't want to use a pile of rivets, would prefer to glue it up.

SikaFlex 252 works great for bonding steel to steel or aluminum to aluminum. We bonded the steel over the window openings about four years ago and they are still fine. We did sand blast all the paint off where the SikaFlex make contact. It's the old story. Products usually work well for their intended purpose, but tend to fail when used elsewhere, no matter how logical this alternate use seems at the time.

I'll second the high opinion of POR-15 for rust proofing. Costly, but it won't let you down. Exam gloves are necessary to keep your fingers from being nearly permanently painted. As to the Sikaflex ... never tried it, but opted for PL Premium instead. Really ... it has held everything I've attempted to glue together (again, wear exam gloves). I bonded aluminum sheeting to my plywood bay floors. As far as I can tell, they are there to stay. Used it as caulking around the edges too and once hardened, the PL Premium appears to be impervious to water and oil. Purchased mine at Lowe's. |

Is there a discount source for por15?

I have used both Sika 252 and PL Premium from Lowes and only years will tell the structural difference. Plus PL is extremely easy to use, shelf life is not a problem as Lowes seems to have a good turnover of inventory and the difference in cost ( about 1/3 of Sika) makes it a very attractive product for my purposes. Comes in several colors and cleans up nicely....I use Xylol (Xylene) and even Mineral Sprits (Sub Turps) will work fine, as will Lacquer Thinner. Sika is very stiff, requires some heat to get it to "flow" and sets up very quickly...minutes, not hours. It also seems to "draw" the material more than PL. In either case, I used tile spacers to separate sheet from structure. Both good products.
