2001 c70 fixing minor holes in your top

[securisign]

I'm new to this site all of your posts have helped me immensely with my 2001 c70, but I've never posted before so if this post is a little wonky just bear with me (or post a link to a resource for how to use this engine better), I'm sure I'll get better with time.
I'm an amateur mechanic and I recently bought a 2001 c70 soft top that had some minor holes (dime sized) in the back of the top near the window and hinges. I looked around on line and could only find instructions for how to repair major rips and other damage that would be leading to a new top anyway. So i went to a local shop that does upholstery and they offered to paste colored vinyl on the holes for $200 . The new top is about 2k so I wasn't completely offended but I thought there has to be a way to get a couple more years out of this top without spending so much. So this thread is what I did, how it turned out in the short term, and a question as to whether I've done something dumb and should have asked all you experts first.

So first I had these little holes forming around the shoulder of the top at the back

So that's when i went to shop and got sticker shocked at how much they were going to charge. Now I'll admit there job probably would've looked a whole lot better, and probably would have lasted longer and sealed better as well, but I didn't have that kind of cash and I only want to squeeze a year or two more out of this top before I replace it.
Went to the craft store and bought 1 $5 tube of instant vinyl, and 1 wooden skewer stick. Dug out some paper towels and an old rag and got it wet to help with cleaning any spills, and cut some cardboard for a palette.

Then i just squeezed the vinyl into the holes and used the skewer stick to encourage the liquid to fill in the holes. I actually did this several times, overall it took about an hour and a half.

When I'm done it still doesn't look pretty but the vinyl patches feel soft and pliable so I hope they wont be a source of tension that just causes the tears to get worse, and most importantly they look like they might help keep the water out of my car and off my leather seats that are too old to handle any more abuse than they've already suffered. Bonus is that I never had to remove my headliner in order to get at the canvas for sewing patches on.

So now I'm feeling all sorts of clever and thinking that this will save someone out there some money and headache, but I have the lingering questions.. Is this a stoopid fix? Should I have done something completely different for a better result? And is there anything more I should do to seal these up (aside from a ragtop cleaner/sealer kit that i already ordered)? If you have any thought please post them, I'm curious about the job I did, and I don't want to give anyone else bad advise thinking it's clever. Thanks for reading!
