Two part Polyurethane over one part polyurethane?

[Nordyfloats]

So I am painting my fiberglass boat. I have selceted interlux's Brightside one part polyurethane for the top half of the boat and am planing on using their Perfection paint on the bottom half. I am doing two colors on the bottom blue over white, and would like to add a blue stripe on my gunwall (over the brightside paint). I am wondering if applying a two party polyurethane over a one part polyurethane will cause problems?

Thanks

It most certainly will.

Re: Two part Polyurethane over one part polyurethane?

The solvents in the two part paint are too strong to paint over one part. One part can be used over two part however. Interlux makes a bootop paint that comes in small cans that you can use to do stripes. Or you can use Brightside to do the stripes.
