Re: OK, so I'm Sanding My Bottom...

Yeah, not too late, but unfortunatly I won't be needing the ace paper...

The 1/3 sheet sander "bit the dust" a minute after I started it up...I didn't even get to do a test patch..it was an old machine, been sitting on the shelf for many years (I prefer the RO) and must have rusted/corroded up from sitting so long...screeched and locked up...

The ACE "screens" seem to be holding up, I did one side the one side of the boat with 4 sheets (2 packs)... about what has been reported in some of the other "sanding" threads...

The RO is using some german made "klingspore" contractor sheets "Finish Line" brand....I only used 25 sheets to get the red off...and I bet I had 15-20 lbs of "dust" in the shop vac...

I will have more sanding to do, got at least one more round of filler to apply and fair out...

Re: OK, so I'm Sanding My Bottom...

Glad your getting there! Sandpaper really varies in quality! The best seems to be available to the auto body business. But, most all auto-body sanding is done with 6" psa instead of the 5" H&L with vac holes in them. Norton bluemag and or green zirconia (3m?) is worth the cost though, I've used it. Home centers seem to sell low quality sandpaper. Also storage makes a difference, long term storage in a damp basement for example,the paper gets soft and weakens the paper's bond with the grit.

Believe me, it did you a favour. That was the first sander I ever bought - it was so horrible I trashed it - I wouldn't even sell it on to some unsuspecting victim. All it did was vibrate your hand - completely useless.

I've been using Klingspore for years on my DeWalt R.O. - they are very good disks.

I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.

Re: OK, so I'm Sanding My Bottom...

It's coming along nicely... two coats of filler dry sand, wet sand and now starting to apply first coat of epoxy barrier coat...

Really smoothing out from the lumpy mess I started with...



And I will admit I have more "gelcoat" layer than I first thought or reported...

The light blue layer was under yet another layer of paint, but is helping me carry a smooth line...there are large "patchs" of filler from previous repair attempts and I guess maybe I was concentrating on them and blinded to how much is still solid...

Re: OK, so I'm Sanding My Bottom...

Now that you've exposed a paint layer, it seems like you are back where you started. You want to know whatever you put over it will stick to it. I'm only speculating that the blue was an original barrier coat. No way to tell from here.

Re: OK, so I'm Sanding My Bottom...

Nahh, I'm way ahead of where I started..another coat of epoxy... two biocide to keep the slime down and I'm going sailing...

Remember this is just fill, fair and seal for this year...too many variables laid down to get too excited over for now...

Seems the only way for "permenant" repair is going to be blast or grind "everything" off down to bare fiberglass matt and "rebuild hull" with epoxy and cloth and then start refinishing from there...

Dollar and time wise may be better off with a different boat...If I'm gonna put $7,000-$10.000 in a hull job on a $3,000 boat I' be ahead to sell this for a $1,000 add it to the $7,000 and buy a better looking $8,000 boat...(or a nice downpayment on a $30,000 boat...)

Fully agree with not relaying the hull.
