primer before applying new antifoul?


Recommended Posts

mechanical sanding vastly improved by the use of a near-disposable drywall sander.

Ozito is Bunnings house brand of cheap nasty power tools, but at only $159 retail this 225mm random orbital drywall sander is great for this purpose.  It has built in dust extraction so you dont need a big workshop vacuum and much to my surprise this feature worked fine.  It comes with a pack of shitty cheap velcro discs in almost entirely the wrong grit range (150 to 400) but getting 80 and 120 grit discs isn't a problem.

You wouldnt want to put it to a professional work program, but for this one-off (and the bonus that I got it at a large discount off a certain buy/sell website familiar to NZ residents) its fine.  I reckon it will do two or three more before it lets all its smoke out.

Where did you get the 225mm discs from?

Got the Ozito and a ryobi  shop vac and hooked up. Works well except for clogging disks which can be cleaned by running it on end grain of soft piece of wood.

Bunnings only had packs of 120/150/180 grit. Prefer 100.

Thanks, works well for my job.

Beats wet sanding.

For what its worth..

I have just had my boat out at the landing for 2 weeks . Had coppercoat but after much deliberation I sanded it mostly off, applied 2 coats of primacon and 2 coats of grey warpaint. Boat looks great for now. See how Warpaint performs in OBC. The coppercoat was 10 years old but in the last 3 years I was cleaning it 2-4 weekly. Never seemed to get it really clean.

Seven years I would regard as exceptional service from AF.

Current service I am accepting is soft wiping every 6mths first year and every 4mths second yr; 3rd yr every 2-3mnths, then it is stuffed. Ultra 2 hard. Westpark/' HG.No scrubbing.

ymmv.
