Greetings everyone. I'm considering spraying the entire vinyl top with a can or two of this black Flex Seal. I've seen some references to the product in a few threads but haven't seen anything specific to a project of this size with the product. I sprayed a small portion of the roof where there was the most amount of wear showing and uploaded a picture of that area. Anybody have experience with the product, vinyl roof repair, Etc, that may pertain to my making a good decision on this? Thank you. Carl

Best to replace or remove the vinyl top if it is failing. Holes and cracks in the vinyl collect moisture and further accelerate any rust that is going on. Holes in the roof panel have rendered many a car to be uneconomical to restore. If replacement of the top is not in the cards at this time, remove the top and apply a good rust preventative to the metal and wait for a better time to do the vinyl.

Don't do it! I've seen it done, it looks like crap! I've also seen asphalt undercoating, that stuff definitely doesn't belong on the top side of a car. And duct tape, both black and original silver, with black being the classier of the two. Rip it off and paint it.
 
i,m not sure that flex seal is uv stable. i tried it on the tube steps on my truck. it turned grey within two weeks.
 
It would have peeled. I tried it to refnish chalky, degraded interior trim. Fail.

IF you don't have the aforementioned rust issue (and it looks like you don't). Colorado is a nice dry climate as well. I'd use some black, paintable exterior caulk to fill the void, then fog the whole top with some semi-gloss lacquer. That's a cheap way to make it better while you save up $$.
 
Back in the later 1960s, there were spray-on vinyl top kits. Dodge even used something like that to do a factory vinyl-look top on their '68 pickups (whose roof had some serious contours to cover!). Didn't look anything like the vinyl roof fabric on the cars. Had a rough texture. The "seams" were replicated by placing thicker strip of tape on the panel before the stuff was sprayed on. Not a very popular option, by observation. Two-tone paint was better.

To me, doing something like that with FlexSeal, once the vinyl top is removed AND the underneath rust is removed/primed/painted. FlexSeal is paintable, per the tv ad fix on the big flower pot. But I suspect that FlexSeal might be a better undercoat material than as a vinyl roof replacement (colored after application).

Just some thoughts,

flex seal sucks. It's a temporary fix no matter what it is installed on.
 
Band aid.

They aren't always rusted. Especially since this isn't on a panel seam. My survivor '70 Fury from California had similar minor damage on it's vinyl top. My quickie caulk 'n lacquer fix lasted about 15 years until it started cracking some more, at which point I just stripped it and painted it. No harm, no foul.

I'm not sure I've ever seen that, interesting. There was also the thickly applied crackle "Landau" roof paint used on hearses.
 
Hey Carmine, thank you for putting the picture of your 1970 Plymouth Fury up there. The hood reminds me of a late 1960s GTX That i thought might look good on my 69 Monaco. My wife has told me that I need to leave the exterior the car looking like it did when it came off the factory lot. That's the way it is now except the tires are a little bit bigger because thats all the tire store had. They're light truck tires or SUV tires which is a good thing because the last two miles to get home is on dirt and some gravel road that doesn't get a lot of maintenance. Anyway, I think the hood does indicate that there's something healthy underneath it the car is just not your run-of-the-mill 4-door!

Your wife is correct. My hood is what came with the car, it was just to show the painted roof. Don't make me regret posting it.
