Staining fiberglass exterior door - urgent help needed!

10 years ago

Ok I really need some quick help from people who have used these products.
I have a fiberglass door stained with Zar oil based wood stain. I did this yesterday.
Last night I looked up the directions for Sikkens Cetol Door and Window, as this is what I wanted for the final finish. (Used the Zar to get the color I wanted first because the Sikkens had yucky colors.)
So now I learn you cannot apply the Sikkens Cetol OVER anything. I called them. It had to be on a primed door only. They "don't know" what the outcome would be over time if I put the Cetol over the Zar wood stain.
Have any of you used the Zar stains UNDER a Cetol door and window finish?

I think they mean they do not know what the color will end up looking like if you use one of the tinted Cetol varnishes. I use Cetol Door and Window over many varieties of stain and never had a problem.

No it wasn't a color issue. It was whether the Cetol would adhere properly to the fiberglass door when put over a Zar stain. They couldn't guarantee it.
So... I just finished putting the first coat of the Cetol Door and Window over the Zar stain on my new fiberglass doors. Now I'm not a professional, but I know my way around stain and finishes; having refinished many antiques and woodwork. Never have done a fiberglass door and wow do I wish I had a wood door. I suppose it looks ok. You know from six feet back...
