Just an FYI from the Blackfire site...
WARNING: S.R.C. Compound is for use on all, newer technology, scratch resistant clear coats. DO NOT use on pre-2005, conventional clear coats. Softer, traditional clear coats should be polished with BLACKFIRE Gloss Enhancing Polish. If you're not sure about your 2005 or 2006 vehicle, check with your dealer to see if it came with a scratch resistant clear coat. If it does have a scratch resistant or nano, ceramic particle clear coat, always use BLACKFIRE S.R.C. Finishing Polish first to try and remove the defect. S.R.C. Compound should only be used to remove deeper scratches and paint defects that S.R.C. Finishing Polish could not remove.
Now I didn't know that there was scratch resistent clear, however their steps are correct to use the least abbrasive first. I have never tried the Blackfire polishes only the sealents and have found them to work good. I have used the entire SSR line and think they work great. In the end they probably will give you equal results. Your best bet is to try them both out for yourself.
