So my old G17 needs its slide refinished and I also want to finish some magwells and small parts. would this duracoat starter kit on midway be a good choice? I am seeing you need to blast it? Excuse my ignorance but is this something the home hobbist should undertake? Do I need to get blasting stuff as well as this? http://www.midwayusa.com/rewriteaproduct/711180 thoughts? Any help is appreciated. I wanted a project but if it is too hard I will just send it off to get done. thanks!
