Stove fuel from Canadian tire: http://www.canadiantire.ca/search/searc ... 4396672077kevinnem wrote:Hey everyone
Just wanted to give you all an update on this. I had a noob experiance this weekend, based on this thread.
I started by spraying it down with "spray nine", and giving it a quick rub down with a sponge, then rinsing off with water. This seemed like the right thing to do as using the polisher on dirt seems like a bad idea. I did this by hand, and would suggest anyone doing this in the future use a mop on a broom stick, and maybe a pressure washer. One huge benefit to doing it by hand is that it forces you to look over the whole of your hull for issue - I found one scrape that is really deep - in to fiber glass. any suggestions on what to "fill " it with?" (on hull, will be underwater, at times).
Then I used the 3m heavy oxidation stuff. I applied it via a 22$ buffer I bought at Canadian tire (aka like a Canadian Walmart). I can't imagine putting this on by hand, the buffer works great though. you need to work in small areas, about 2 foot by 1 foot because you need to wipe it off as soon as your done polishing.
I have not worked on the topside yet, but as for the hull it was a HUGE success - it easily took 10 years off the apparent life of the boat. on the top side I will be using the starbrite non-slip cleaner- and also have some compound form 3m for the rubber rub-rail.
we did a bunch of cleaning on the inside as well (it was trashed), it is looking a lot better now. a few more noob-questions came up . like for example,
Is there a built in bilge pump?
What fuel does the "alcohol" store use? I was at the store in the camping section and all I could find was "white gas" (naptha) is that the same thing?
I did have a sort -of rough brush , and was thinking about using it on the hull, and topside - I felt it was a bit harsh for the hull, was I wrong?
My boat has bottom pain on it, and it seems even thought it had been washed, every time my sponge, or buffer hit it, it would suck some black off it- is this normal?
next Sunday, I am putting her on the water, so it will be the challenges of rigging, and the motor (also have to rebuild the roller fuller). FUN TIMES!
You sound like you have anti-fouling paint on the bottom. It definitely should come off if you brush it. It is designed to flake off in bits while moving if critters try to adhere to it.
Regarding the brush, I have thought the same thing - but I use it anyway. A sponge is probably way better. The brush is definitely the only thing for the topside anti skid surfaces.
Bilge pump is not standard. It would have had to have been installed later. Not a bad idea if you have through hulls.
Rigging - take your time and keep looking for snags. Don't force anything when raising the mast.
