Paint Removal with Pulsed Laser: Theory Simulation and Mechanism Analysis
Round 1
Reviewer 1 Report
The paper proposes a possible mechanism for paint ablation, substantiated by simulation and experimental study. The paper is interesting and scientifically sound. Some possible improvements are listed below.
In the introduction section, the applications of paint removal should be included Material and Methods, line 62: it should specified why the model includes an oxide layer Line 75: 1024 nm or 1064 nm? Figure 2 is not cited in the text line 105: "the temperature field that had not cooled…" please remove "that it" FTIR analysis: the attribution of all FTIR peaks is not necessary and can be reported in a table. Only the absorption bands that vary should be mentioned. The differences are really very small and barely perceptible. A zoom in the regions of interest could aid. Line 183: "Figs. 4, 5, 6 and 7" are Figs. 7, 8, 9 and 10. Line 188 figure 4 is figure 7 Line 225-226: "which can be attributed to that…" the sentence is not comprehensible Surface analysis: a SEM image of the untreated surface would be useful for comparisonAuthor Response

Reviewer 2 Report
Line 32,33: Please reformat capital letters inconsistency on the beginning of the sentence.
Line 75: energy density 17.26 J/cm2, is this average density considering it is the pulsed laser beam, or during lower pulse level or higher pulse level?
Line 69, 81: Please define chemical composition of the aluminium substrate to ensure the repeatibility of the experiment and to analyze the posssible influence of alloy elements.
Line 81,88: If material size is 15x15x2mm, how thickness of 3mm is declared in line 88?
Line 102: High speed is 600mm/s? Please explain…
Figure 103. Please mark the length distribution (x axis), only temperature is presented according to scale, while there is no data of distribution through x axis?
Line 351, 352: Please explain is it possible that base material decomposition could influence the chemical spectra (not only the paint)?

Reviewer 3 Report
The parameters of laser action (intensity, pulse duration etc.) are absent? I've noticed the laser radiation wavelength only in "3.6 - Discussion". Those parameters are main for understanding of an experimental and theoretical results. I recommend authors to change the describing of discussion. It is true that : "Laser cleaning of paints is a very complex process", but you need to describe step by step laser-induced process more clearly (may be added typical time for each process and depth of absorption layer etc.)
