I saw alot of banter about the quality of the canopy masks online, but i never saw any of the issues people claimed they had. They went down well, there were a few ridges where the vinyl bent and joined, but they did exactly as advertised, they masked the area from receiving paint, and they did it well. No residue, no overspray.
The marking masks worked the same way, thinner material was used, and clear(smoke tint?) instead of black. They lay down nicely and came up nicely leaving sharp lines that blended nicely into the rest of the paintwork. I had a few issues, but i think it was because i lifted them too early while the paint was a bit tacky so i got burrs in some places.
Overall ive so far had a very nice experience with them. The only issue i have is theres no real instructions in the pack, so i get a sheet with 4 different canopy masks on it and no indication of how theyre to be used, so i guessed. (Turns out theres a mask for interior and exterior for both the galland and regular canopies)
Another note is the set i got was specifically for the kit i had (Tamiya) and they fit perfectly.
I was going to post photos but i checked my phone and i havent taken photos of post masking. Ill get those up tonight.
