Title: calling Mike Winter
Post by: OhioTed on December 23, 2009, 07:03:58 PM
Hi, Mike.  Could you please check in on my graphics inquiry?  Also, I have send you a PM.  Was hoping to ask you a few specific questions about applying POR15.  Thanks.

I just read this part of your request, but I have been keeping up with the story about a tank skin on the adjacent thread.
The tank skins were made to cover plastic tanks, the reason of not being able to repaint the tanks because of their inherent nature of gas turning them dark in color and bubbling off the decals and most attemps at painting them as well.
This usually isn't the case with fiberglass tanks, but with the newer alchohol mixed fuels, problems with bubbling has drastically increased within the past couple of years. I know Don at DC Plastics has his hands full with current projects, but this may be something he can work on when time permits.
As for myself, I would simply do a thorough cleaning of the fiberglass tank with lacquer thinner followed up by MEK and coat the fiberglass tank with 3 or more coats of POR-15 and even sand and coat the outside of the tank, then sand and repaint the tank and put on decals and forget about it, as I have nothing to report on the POR-15 except it has provided excellent results for me so far. I will continue to experiment, but I stongly believe that this is the cure. Mike
**BTW, I think that the PM is still not working on the site**

I enjoy rebuilding and appreciating Pentons!

Thank you for your additional input, Mike.  A few questions for you:  
In the prep-steps you outline, what is "MEK"?  

Also, when you describe using the POR-15 product, you mean their "paint", correct?  I am not familiar with the POR product line, so I don't know if they have a specific tank-sealer.  

Finally, what paint are you using over top of POR-15?  My understanding is that it is difficult to get paint to stick to a POR-15-coated surface.  Also, is the paint you are using specially-formulated to adhere to non-metal surfaces?

I will start a new thread titled, Coating a fiberglass tank with POR-15 Clear, look for it, since it is very detailed. POR-15 will adhere to almost any surface with the exception of plastic or rubber and can be used for fiberglass repairs with fiberglass matting in place of fiberglass resin and is very strong once cured.

Mike, you use the clear? My Dad uses it on his Mustang car restorations to seal rusted spots on frame rails.

EDIT: nevermind I just read your new post.
