I've been strongly considering purchasing an hvlp system for purposes of spraying clear. I found a thread on this site where a few members have said that Sherwin Williams Lovoc can be sanded after 4 days. I have been using Reranch products, and they are good, but if there is something out there that hardens in 4 days vs 30, I've got to try it. Also, when spraying Reranch products, I'm following the rule of 3s. If you want to get 12 coats on - which I've a read a lot if people do - you're spending 2 weeks applying clear. If I were to use Lovoc, per one of the threads on here, I'd only need 3-5 coats. I assume that has more to do with the way a gun can apply the clear vs. rattle cans. So, the questions I have are: 1. Can you really get enough clear on with a gun using Lovoc in just 3-5 coats? 2. Can you really start sanding after 4-5 days of curing time? 3. What are the rules when using a gun system - would I put all 3-5 coats on in one day? How long between coats? I'm just wondering what the process is with a gun since you need to clean it after you're done. Do you spray one coat, clean the gun, spray another coat, clean the gun, etc. Thank you for your help. This is my first post.
