I know Mar-K is testing Por-15 and black Bear paint. I'm wondering if anyone can comment on Por-15 for the primer and the Por-15 product called Top Coat. It has UV inhibiters. I found a reference that Top Coat used to be called BlackCote if has experience under that name.

The surface looks nice. http://1954advance-design.com/Web%20images/COE-Photos/bed-paint/4-bed-fr-4th-coat.jpgCoat 1 - POR-15 semi-gloss Rust Preventative Paint (wait 2-3 hours for firm tacky surface) Coat 2 - POR-15 semi-gloss Rust Preventative Paint (wait 2-3 hours for firm tacky surface) Coat 3 - POR-15 Chassis Coat Black (let set overnight) Coat 4 - BEHR PREMIUM PLUS ULTRA Exterior Semi-Gloss Enamel Process: 1. Prior to rolling-on the first coat, we "cut-in" with brushes between each board (to get to the now-exposed-by-weathering tongue-and-groove "openings"/separations). 2. Apply with rollers the first three coats (liberal application, rolling about three feet front-to-back, side-to-side, and again front-to-back). 3. Before applying the 4th/final coat, "cut-in" with brushes between each board and then apply with rollers. | | | | | Joined: Aug 2000 Posts: 1,438 'Bolter | | 'Bolter Joined: Aug 2000 Posts: 1,438 | Sounds like a good option Tim. I'm doing this before putting the bed together. I think I will do the bottom/sides/ends first. After doing all coats with that then flip it and do all coats on the top. I'm curious why you switch to the Chassis Black and not another coat of POR-15 semi-gloss Rust Preventative Paint. If you were to do it again, would you still choose the Behr instead of a Por-15 product with UV protection?

I tried to follow the procedure/coats that were/are described on the Mar-K website.
I might have used the Chassis Black as the third coat only because I had enough left over from doing the chassis (waste-not, want-not?)?
The POR-15 exterior coat paint is probably quite good. The Behr paint was used in the procedure described on the Mar-K website. | | | | | Joined: Aug 2000 Posts: 1,438 'Bolter | | 'Bolter Joined: Aug 2000 Posts: 1,438 |

It has been a couple years and still looks good, but I am not convinced it is better than the Behr product tested. Incidentally the test Behr black finish is still in the weather nearly 12 years 24/7 and looks almost as nice and shiny as it started.

It's funny as I'm just now getting to painting the boards. That is all I was going to do this go around but I couldn't stop taking things apart!
