Sanding/repainting a trailer
 
I'd like to repaint my trailer, but to do this, I need to get the old paint off first.

The trailer has only surface rust, none of it has broken through and there are not holes.

Now, I've always been told that I need to sandblast the paint off. I've gotten some quotes and it's EXPENSIVE. I can rent the equipment, and I can probably find a place to do it, but I've never used a sandblaster so I'd be concerned about accidentally damaging the trailer.

I was thinking, could I use some sort of sander, like a belt sander or a rotary sander and get the old paint off? I understand that it would probably take a lot more time and I'm sure I'd go through a lot of pads, but I'm trying to stick with my level of ability.

Id go with an 4.5" angle grinder with a screw on wire brush, bout $80 bucks at lowes, you can also use chemical panit strippers and heat guns but you will still need to wire wheel the rust spots, then you gotta use a rust killing chemical, then prime and paint.. Its a pretty big job, Id find a paint shop.

The quotes I've gotten were all around $2000 to strip and refinish the trailer :( that's why I'm trying to find a way to do it myself

GO for the angle grinder and wire wheel, take you awhile but it will work, get a couple different shapes of wheels. Find a boating or marine type store to get the rust killer. Its a paint like stuff that kills the rust. You still need to wire wheel it good first,,, scrape a days worth then put the rust killer on it last, next day continue scraping till your done.

Thanks, Joe. I'm actually going to print this out so I can take it with me when I head out. Now I just need a few days of clear weather!

That's the way I'd do it.

DON'T forget safety glasses. An angle grinder is going to throw a lot of stuff at you. You may want to pick up a full face shield and dust masks too.

and good gloves, those wires do a number on skin, yeh dont even think about turning on a wire wheel without safety glasses, not even one second, with use some of those itty bitty wires sling out.

boaters world used to sell a paint called "trailer coat" it was for boat trailers launching in salt water. Worked well, kinda a rough finnish so you could top coat with a colored paint if you want to the trailer coated didnt need primer, Do not get it on your skin as it will not wash off with anything once dry. Kinda pricey and I would assume a decent zinc primer and paint would be fine for a trailer not getting submerged in saltwater.

despite the description you still need to wire wheel any rust off, you just dont need to get insane about it.

I could have sworn I made another post in here but I think the Internet ate it.

So....wire wheel the old paint and rust off, primer (how many coats?), then paint (I was thinking rustoleum? Any other suggestions? Am I stuck to spray cans?). Is that the right order?
