Any experience with Eastwood's Optiflow roll-on primer??

I have never used this product, but I would and just might. In my opinion it looks like a well thought out, quality and viable product. Remember time is money and spraying has to be way faster, but if you don’t have the skills and and/or the spray equipment, this looks like a valid option for a do it yourselfer. If you don’t plan on painting a boatload of cars, it probably will save you a lot of cabbage in spraying equipment. The only downside is finding a quality body shop that will finish coat your prep work. I would believe the last thing a quality body shop would not want to stake their reputation on a finish coat gone wrong because of your bad prep work.
