17" boat, I have all the materials to repaint the bottom. I will be spraying it on with a professional gun. my question is any tips or tricks for this. it is sitting on a trailer. my thought was to paint what i could get to, wait for it to dry then roll it back on the trailer and get the rest. how does this sound?

Re: Need Tips on Bottom Painting

For the best results when bottom painting,

Try to get her to moisturize for a few days before the session, and make sure you have enough lighting and light filters to adequately show off her assets. A soft glow is best, and when first marking the canvas....

Oh, a boat?

If you're spraying, be careful, because a lot of the semi-pro paints are meant to be rolled and tipped nowadays, and they're toxic stuff.

For a boat that size, I'd recommend getting it off the trailer completely, there are posts elsewhere here on how to block it up using the trailer tongue jack. If you do it in sections then you may end up with a blotchy look depending on how good you are at duplicating paint work and blending into the old.

Wet down the surface below the boat just before painting to keep dust down and also to keep paint from adhering to your driveway or whatever.

Prep is everything. Sand and clean before painting, fill holes, fair the hull, and generally make sure it's the best surface possible if you want to make your paint job look nice. Prep work is about 95% of the paint job.

Go for several thin coats, not one thick one. Keep the spray gun moving. Follow closely the paint manufacturer's directions on thinning and application temperature.

Getting Boat Off Trailer

you don't need stands.

1/you can lower the tongue to the ground. i would get some 6x6 or old railroad crossties cut the +- 12 inches, now block up the transom. 2/

Raise the tongue of the trailer the back of trailer will drop away from trailer. this is the tricky part. between the cross braces of the trailer block the keel lower trailer, boat will be suspended on the blocks.

3/ pull forward, lift bow again, and reblock i a different place. repeat until trailer is out from under the boat.

4/ to reload, just reverse the procedure.

if you were just working on the bunks, or painting the bottom. you could just do the first 2 steps.
