Very dirty paint, my friend. You have to strain paint before you try to use it in an airless sprayer. But it like old like you got it done. Congratulations, it looks good.
I was looking for a paint strainer before I did it but was not able to get one at the store and thought to myself, I'm just going to give it a go. After a while I did thin the paint somewhat and it worked out great in the end.
Them big holes were fixed... they no more!! I was in a rush to get the video out but went back and patch them holes up. Also I thought it was a good idea to first paint then patch and paint again. No worries mate the rust will not come back soon.
