This is a follow-up posting to my Great Customer Service posting. Paint day has come & gone. Here are the results.
The sample paint was a 340g rattle can of Old Caterpillar Yellow manufactured (or distributed) by Rust Check. The test areas were the left & right side panels from my Allis HB112. The areas were prepared by: 1) scuff sanding to various degrees of bare metal with 100 grit paper, 2) soap and water wash, 3) Methyl Hydrate rinse, and 4) drying. The drying room was temperature controlled at 20*C (68*F) and 37% humidity. Except where noted below, the areas were left to dry for about 90 minutes between coats.
Impressions: The spray nozzle is of the standard design, but has the wide horizontal slit which gives a vertical fan spray pattern (don't ask me how). It is, therefore, prone to the "painted trigger finger" flaw. The wide slit / vertical spray pattern took some getting use to, as I am more use to the Tremclad round hole which gives a conical spray pattern. The major difference is that the conical pattern gives two coats with each pass (leading & trailing edge of the cone) whereas the vertical pattern gives only one coat per pass. This allows for thinner coats, but that has its own drawbacks for this paint.
That drawback is related to the drying time between coats. Tremclad and other rattle cans have a 1-2 hour re-coat window: you can re-coat within the window or after 1 or 2 days. This means the paint is still tacky, or non-dry, when the next coat goes on. This paint has a 90 minute no re-coat period: the paint must be completely dry (90 minutes) before re-coating. While this liberates the painter from timers, it dramatically increases the overall paint cycle when combined with the single coat per pass mentioned above.
So, how much does it extend the paint cycle? Well, I needed 6 coats to get a satisfactory covering. For you with Arithmophobia (math-phobia) that is 5 drying periods, or 450 minutes, or 7.5 hours. Mine was extended even further in that a sleep overtook me between coats 5 & 6.
As you can see from the pictures, my coat count was likely excessive in that the coats are on the thin side in an effort to build layers without getting runs. Eventually, I will get to know how thick I can make a coat without getting runs. The last few coats were thicker than the first few.
Before coat 6, I took some time to examine the results and compare them to a control area I did with Tremclad Rust Paint (Gloss Black). While the Tremclad only took 4 coats & 90 minute to paint, it was still tacky after 18 hours of drying. The Rust Check parts were dry and hard as nails. But for the colour sanding & polishing, they were ready to install. In the end, the Rust Check paint was faster from start to install, even with the higher coat count, and the end result will be equal if not better.
Recommendation: I like the paint and will definitely use it again.
