I must be reading your mind. Looked all over for a good sealer and settled on a product called Restore for wood decks.
Pricey but you get 2 gallons and I used close to one on 2 coats of bottom & side paint. Almost thicker than Molasses in winter but definitely the right product for this sort of application.
I did not like the roller that came with it because the finish looked like knock down so I got a short nap that I used after brush stroking the angles.
I was able to cover joints that got missed during manufacturing and some pretty good gouges just forward of the bottom tin.
Also noticed some joint separation on the left hand rear area 6" inches in from the side running forward from the tin for about 8-10 inches.
Sort of validates my impression that the bottom structural strength of the camper runs along the outer area 3" on the side and bottom and my logic behind creating a 2" x 2" angle frame to sit the camper in.
Yup it is a semi permanent mount and right before its mounted I have 5 tubes of "leak stopper" to go on the angle frame. It will be messy and squirt out everywhere but thats what I want.
The bed and frame got an acid wash yesterday afternoon, then it rained last night and why it looks white but I think we are good to go for paint and undercoat tomorrow after prepping.
I have not worked through the tie down yet. I do not like how the jack pads were installed with just washers and no backing plates, you can see the bow. Too much stress on camper.
Initially I was going to just rotate jack pads so the pad face sat inboard and tie down from there to stainless eyelets mounted on the flat bed but now I will buy more eyelets and stainless exterior and interior mounting plates. Stronger and less stress ( I think)
I was in UH-1B,C gunships in a time long ago in a Galaxy far, far away.
