I have a few very small nicks in the white vinyl but the are into the fabric backing.

This is a heat activated fix: http://www.jlryan.com/Main/product.a...e=HWLLPROVL-50

There is also the cold fix version that does not require heat to cure the patch material.

Has anyone used either for such repairs? Results?

I would be interested. Ive got some small stuff on my drop down bolsters. Bill, you keep your boat on the lift all winter?

I would practice first on some test pieces.

Sounds like the same process that Dr. Vinyl uses.

I have done both and an expert an neither. The hot patch worked and stuck pretty good. Color matching was a PITA. Mine repair was not in a visable area so it was not a big deal. The cold patch method never seemed to cure right and felt tacky.

I used the same type of kit from WM to repair where a rope rubbed through to the cloth backing also. The repair looked really good at 1st (match and texture), then the coloring lightened up a little over time. I was only using the red as it matched really good. It was almost undetectible at 1st, then really only if you knew it or happened to look right at it. Didn't jump right out at ya.
PRACTICE on scrap 1st! The sample grain papers are pretty good (close) but you really have to watch the amount of time you keep the heating iron on. Just a bit to long, then the vinyl gets to soft and loses all grain, just a smooth texture. Also makes it brittle if left on too long.

My repair was on the fairing trim covering. A high visable area, but not a high traffic spot. Not sure how well it would hold up on a high wear spot as a seat bottom.

All said and done, I was very pleased with the results.

Yes, going on four seasons now.

Good to hear this works well. Can you give some guidance on how much is long enough and how much is too long with the heat? I will be practicing.

I am going with the hot patch then. Thanks.

Been several yrs since I did it, so can't recall.

You'll get a feel for it after a couple trial runs.
Good luck.
