My scratch built expedition style trailer build up thread (1 Viewer)

[REZARF]

Now that the body was as good as it is going to get, I started the first step in painting my little trailer... the underside.

I chose to use a 3M rubberized undercoating that cannot be top-coated. It is great stuff and sprays on a nice texture. I used 3 cans total, about 3/4 of a can on the little box and another 2 1/4 cans on the big box. I sanded the bottom of both boxes with 220 grit and wiped everything down with acetone before spraying. Here is a close up of the prepped metal.

I did use one of those little spray gun attachments to spray the rubberized undercoating from the can... it works great, cheesy, but they work great.

I put on about 4 coats onto each box.

Came out looking nice and rubbery!

Here is the final result, not too shabby.

Tomorrow, I am going to flip the box over, hose down the garage, hang up some plastic, wipe the poo off every surface, and spray this thing blue!

Wish me luck!

Drew, where did you purchase the 3M rubberized undercoating? How much?

 

[Degnol]

Most any autoparts store will have it...

I know you are well down the design path. But I haven't been able to keep up.
Two things.
I found this on another site. It's a way to drain and fill the water tank I thought was well done.

Also,
On the fenders. I saw the way you mounted the fender to the sheet metal. It looked like to me it might cause the metal wall to flex when you do some bumpy roads. Essentially the fenders might, ever so slightly "flap" like wings on that wall.

If you tacked the top to the center support you could eliminate a bit of flex there. It's just an observation.
I marked the supports in red.

Corbet, I bought that stuff at NAPA, for $5 bucks a can. There is some more expensive stuff (see the link above) that is the same stuff but can be top-coated... no need for that in my application.

Hope it helps.

Thanks we will see how it goes, I am using large fender washers on the backside of the panel so I bet they hold pretty good. I mounted them up and saw very very little flex... I can live with that!

Well, I am taking a break letting the primer flash... man I am high on fumes! so I thought I would bump a quick post, here is a breakdown of my day.

First up, wet down the floor and shop vac it clean and shiny... and dust free (mostly).

 

[REZARF]

Next up is covering all I can with plastic sheet to avoid the over spray from taking over the whole garage. I used a few drop cloths from Home Depot and it made short work of masking off the rest of the junk in the garage...

Then I made sure to have everything in place before getting started, here is my handy dandy workspace... it was nice considering I spilled a good bit of primer when I first got going, I will be nice to just scrap it and lay down new sheets when the time comes.

 

[REZARF]

All the parts in primer!

 

[REZARF]

more, more, more... kind of a cool color for just primer, I have always loved flat paints

 

[REZARF]

Now I have to go fill all the gaps with an acrylic sealer to make sure this thing is water tight (more for rust prevention than anything else and then I am calling it a day! I will have to wait for the weather to cooperate to paint it blue, maybe Friday or Saturday.

I'm simply not worthy!!!!!!!!!!!!!!!!!
Freekin Amazing!!!!!!

 

[Acadia]

hope you have the garage door at least partially open when you are spraying that thing?

 

[Degnol]

Drew, looks great! I may have missed this but what kind of primer are you using? Catalized? Urethane? Lacquer? Keep the floor wet and all the overspray will sweep right up.

Thanks man, the shots don't show how it truly looks, nice, but not awesome

I spray the pieces, let the primer flash, then vent the garage as I get out. Repeat.

Self-etching urethane primer from Sherwin Williams, I can grab the exact part number if you want it, the can is still in the trash can. Yeah, good tip on the wet floors.


No blue today , the weather started getting rough, the tiny ship was tossed, and my temps dropped like mad, snow in the morning That is cool, now I can go over it with a light sanding, and seal all the seams with some acrylic then have it ready to squirt later this week once the weather clears up.

Good deal on the fenders.
I was worried about that...well worried? I was concerned. Hopefully some day I will get to make my own trailer and you can bet it will incorporate a bunch of the design techniques you are using.

What did you think of that guy's drain and fill method. Simple.
