When to Sandblast Bottom

[C-SIDE]

Great advice Carver370 - perhaps I'll see you on a Spring Sunday in 2010 :thumbsup:. We can then go have a beer

I cleaned-up my stern drive a few weeks back. did you notice the before and after?

Thanks again for everyone's input!

You know I actually did, and I saw you doing something over there. That must have been when you were doing that!

I was helping out with packing up the blow boat across the street and I came and went a few times in a black Navigator.

I am usually doing stuff to the boat year round, I have a small oil filled heater that I use when Im inside the shrink wrap that actually does the trick depending on what room I am in. I will probably hit the water ASAP end of March - early April. They stored my boat along the railroad tracks by the large brown building parallel with Oselka Drive. Can't miss it.

when I'm up there I'll look for you - pretty hard to hide a 37 foot Carver

I think the problem is the first time some places paint the bottom they don't sand the hull so the paint does not bond properly. Over the years of re-painting layers of paint build up over layers that never bonded properly so it becomes a problem. From what I have been told, if you prep the hull properly before the first application of bottom paint you should not have many if any peeling problems.

For the record last spring i rented a wetsand blaster that attaches to a power washer and stripped the three layers of old bottom paint from my 93 2655 bayliner (for sale )It took two days in the driveway and another half day on blocks with a sander at the marina.I then wiped it down twice with interlux 202 solvent and applied three heavy coats of pettit epoxy ,two coats that day and one the next morning .Four hours later i applied three coats of hydrocoat by pettit.Plopped her in the next weekend and when i pulled out in the fall she could almost be rinsed off with a hose .Ps i did the same on my 40 silverton convertible in2003 and swore never again !!!I use all interlux on the silverton with the same results.Best advice ,dont do it all in one weekend or even two my back still hurts.

I kow nothing about sandblasting fiberglass but a lot about sandblasting steel. An inexperienced blaster can cut a hole in steel with the worng sandblating method. I assume the same is true for fiberglass. Get a good resporator or in 15 years you may feel like you smoked 2 packs a day all your life. The same goes for the paint fumes get a mask that is rated for the task. You should get eye protection gogles not just safey glasses. good luck let us know how you make out.
