    Dont hold your breath
    I dont like the vehicle wraping, because it looks Odd to me,...although a great idea for bus. advertising, but to make something look as if it were painted or customized (i hate that word!) you cannot compare to paint, the lines are not blurry or you dont have the screen looking lines throughout the entire posterwhen using paint! just my opinion, but back to the original question?... if it were my boat that needed to have all of the checking repaired, i would grind the deck to glass lay 3 oz. of mat and start blocking the apply gel to ultimately have a non-repaired looking deck!
    Just think about the guy who will be the next owner of your boat, will he llike it to be vinylized or repaired right?

    Jeez, am I glad you said that Todd. This is essentially what I did but I used WestSystems epoxy. The whole time in the back of my head I've been hearing "john, you phucked up another thing. shouldnt have done that dumbass". It's scary to do but looks dam good now....

    Nothing to write home about. It's still a work in progress stage having done this repair and also an attempt to cap the boat as well. Getting close to starting to shoot some surfacer on it and begin blocking.
    I'll certainly post these early pics but don't know how they'll look without it being finished and painted. I hope to lay the last layer of epoxy on this weekend.
    Here's one of how I ground it out and one with a layer of glass and epoxy before I sanded it out.
    In the first picture the cracks were in the area inside the circle of fabric showing.
    For the record, I DO NOT know what I'm doing but have spent alot of time asking questions and performing searches on this and many other sites.

    I had some of the same cracking that your talking about on my deck and I sanded it good with some 60 grit and cleaned it real good with acetone then filled with gelcoat paste and a putty knife making sure to get it into the cracks then i sanded it primed it sealed it and painted the whole boat. but I think that I should have cured every step with some heat because i did this all in the cold of winter and when it was done it looked good until i rolled it out and let it sit in the hot sun for a couple of days and it shrank up really bad and you can see where the cracking was so either it needed to kick off better or you have to sand off all the bad gellcoat first. Im going to give it one more shot with some filler and make sure it has kicked off good before I put any paint on it and see what happens. I get all the mateirials for free so im not out that much if it dont work and pluss who the hell is going to see it when your doing 100 mph anyway?

    I've done 3 boat's with this same problem..if I was gonna pay somebody to do MY boat then I would want Todd to do it!! but since I live on the other side, that won't happen so..Here's the way I do it 80 grit, High Build POLYEYSTER-PRIMMER-SEALER, sand it with 180,POLYEYSTER-PRIMMER-SEALER, sand it again with 320,repeat if needed , final sand, block with 400 W/D and base it, Clear it, wet sand,buff !!!! sounds easy
