I just picked up a MM hull on ebay cheap, BUT, it has a couple small cracks on the bottom of the hull in the tunnel area about a inch long. Somebody just dabed a bead of glue or epoxy over them, looks bad, and not smooth, and there is a ton of holes in the transom, from probally a bailer, pipe and hardware. Whats the correct way to fix these, and get back to a smoth finish?

Is there a type of filler I should use to fill the unwanted holes?

I used west systems G Flex, It's a 2 part epoxy, You can get it at west marine or via the internet, If you have a west marine around you, also pick up some coloring agent, they have it in a variety of colors, I've found that if you do use the coloring agent, you have to add slightly more hardener to the epoxy mix, once it drys, you can sand and buff for a perfect finish

I have some of that and zpoxy epoxy and zpoxy finishing resin. The G glex sands well? What and where did you get for a color agent? After reading again, I guess you got the agent from west marine.

I use Marine-Tex for blueprinting and as a filler.

If you can't find a filler you like/color you find to be acceptable, have you thought about painting the bottom of the hull? Many guys are using krylon fusion paint but it doesn't bond well to fiberglass, ace hardware sells Appliance Epoxy paint in white or black, requires no clear coat and gives you a really nice shiny finish that will last. The stuff is fantastic and extremely hard/durable. Its like 6 bucks so I figured I would throw it out there if epoxy dye/shipping costs you too much. West marine sells an additive for their 2 part epoxy I forgot the number but it sands extremely easily and costs about 10 bucks at any of their stores. I use it when filling/blending the seams on bigger boat hulls.

Yes thanks, Thats probally the way to go, I can do the repairs, sand it, and paint the tunnel and transome black or white.

After you've spent time sanding/filling you'll still feel unhappy (if you're like me) with the appearance. Check out ace hardware and some of appliance epoxy paint, sand with 220 grit before painting and you'll be good. I know you're in NH so find a way to paint inside or on a day when the temperature is 60+ degrees, paint won't flow well and you'll get a very orange peel finish. This stuff requires no wet sanding afterwards I usually paint get a nice flat base down with sanding between coats then a light final coat after warming the paint can under hot water. No reason you can't get a professional looking finish with a 6 dollar spray can.

Helpful tips.
Last time out my white Revolt hit the cinder blocks coming back in at the launch area. Ouch! Hey, things happen when testing three props in 10 minutes.
Thanks,

Yes but it's a bit smoother and less viscous than a putty. Sands nice, cures hard and bonds well. Comes in white, gray or black.
