Tanto mi papá como Carlos eran sólo un par de fardos tirados sobre la cama. Mi papá boca abajo y el otro, boca arriba. No eran muchas las expectativas que se podía poner sobre ellos en esos momentos. Sólo se oían sus respiraciones ir de mayor a menor conforme pasaba el tiempo, y yo los observaba.

Test Method A is primarily intended to be used in the field, while Test Method B is more suitable for use in laboratory or shop environments. In addition, Test Method B is not considered suitable for films thicker than 125µm (5 mils), with the exception of wider spaced cuts, as detailed in the ASTM D3359-23 standard. The paint scratched off. I sprayed the primer but brush painted the paint. I’m assuming the scratch test should be done in all areas including edges. I waited 2 days after painting to scratch test. Any advice? Reply. Annie says. April 10, 2023 at 1:59 pm. Denise, hi!
