Well, you can do it yourself if you know how, what to use, and have the time. I chose not to attempt that even though I consider myself a good painter, and I am retired and have the time.
Here is the deal:\
1. You must prepare the surface after removing all, all the hardware
. To do this, you must remove the mast
2. You should sand blast or sand the entire mast and clean it.
3. You should chose a good paint
and follow the manufacturers instructions without shortcuts or deviations or the product will not work properly.
4. You mentioned powder coating; this process should be done professionally and requires serious prepping and a booth that can handle the size of your mast. I don't recommend that process.
5. Painting the mast is more logical for the size I believe yours to be.
6. Next is needing a clean environment
to remove the old paint and not violate any clean air and water regulations
to avoid the obvious EPA people.
7. Most marina's will not let you sand and paint in the air if they are rated as a clean marina.
8. So you get the above accomplished successfully, and not you need to re-install the hardware
. This requires using a marine
grade silicone and a preparation material to deal with the dissimilar metal contact with the mast and hardware. I can't remember the name, but it looks like mustard.
9. Assuming all is going well to this point, you will spend several hours or days shaking down the reinstall and tuning the rig until all is settled down.
Ok, I know this sounds like doom and gloom. But it's a project
that takes a lot of equipment
and time. My experience two years ago was somewhat painful and expensive and I am merely passing on the info and lesson learned. I have a 82 foot keel
stepped mast that also has a Hood Furling
system inside. I contracted JSI in Tampa to prep and paint the mast for about $5,600.00. Because of the size, I was forced to contract
a escort trucking firm to haul it from Palmetto Florida
to St. Petersburg Florida
where JSI had a 100 foot oven
to bake the finish. They sand blasted the old paint, prepped the surface and applied three coats of Emeron. The escort cost to travel 35 miles one way, cost me $3,000.00 round trip. The removal
and replacement of the mast cost me around $6,000.00. I have no blisters
and the paint still looks new. The blisters
will occur if you use the wrong materials for re-attachment of hardware.
Then there are those little add on's that while you are this far along, it may be prudent to look at fresh halyards, new lights, horn, radar
, bird deterants, mast boot, cables
It was worth it on my boat, but I'm anal about appearance and budget
these projects in advance to tackling them and all and all, I came in on the budget
with the exception of shake down issues.
Good Luck if you do it yourself, but I would rather be sailing.
