One part polyurethane question

Hello All - I am touching up the transom on my Alberg. She is getting her original name back but the current name is painted on so I am sanding it off. It has a discernible thickness.Her portname is also painted on and I am attempting to keep it. I have carefully masked each letter with frog tape. I am using Brightside one-part polyurethane paint. Will there be any problem getting a clean line with the tape because of the hard film of the finish product? In other words will the paint span the seam in such a way that the tape will not release cleanly?

Re: One part polyurethane question

It helps a lot if you peel the tape off as soon as possible. I.e. Before the paint drys

(Cute name).

As you are a relatively new member here, let me tell you we have a few really knowledgeable guys as members...minaret and maine_sail come to mind, but there are others you can discover via reading their posts. Often a Personal Message (PM) to them can lead to a really helpful answer.

I only know enough to know you're right to be concerned, but not enough to recommend a product to you that will allow you to do what you want.

Re: One part polyurethane question

Use 3M green masons tape. Not the usual green tape, it looks exactly the same but the inner ring is purple instead. Costs quite a bit more. It is designed for making crisp lines when painting rough cement or even stucco. Rub the hell out of it and then work over the area in question with a small stiff bristle brush. The edge of a cheap plastic spoon is also an excellent fingernail substitute for rubbing out tape.

One part polyurethane won't last very long. It will fade out in no time.

Also consider vynel letters for the name. Lasts a loong time on my
Alberg at least. Over 35 years now.

Re: One part polyurethane question

Not sure how well your painted part will match the other. My impression of Brightsides product was not good on the things I used it on. Personally I prefer paint old oil based enamel to brightsides. Not that I like either that well!
For clean edges, remove the tape before the paint sets up. Auto repair suppliers sell "fine line" tape which works great for clean edges with no paint bleeding under the tape... that's it's purpose... for great edges on autos.
I too agree.... paint the whole transom and get new vinyl port of call. Vinyl boat lettering is even on ebay... I've used them too... no difference from the "Marine lettering " that is so highly overpriced locally....

Re: One part polyurethane question

I agree with the advice to paint the whole transom. I also switched from Frog Tape to green masonry masking tape.

Just to be the contrarian, I've had pretty good luck with Interlux Bilge and Brightside. I got Sedna's Vinyl name and port letters from BoatUS graphics... They arrived quickly and I even got their guaranteed replacement when I ( my fault) messed up the port of call installation.
