I'm looking for some customer reviews on house of kolor products. I am planning on buying their KD3002 primer for my roof and BC25 jet black base for the rest of the body. For the base coat colors I want (also HOK) I was told that these would be the best primers. I have heard that HOK KD3000 series primers double as primer and sealer. So I should be able to apply the first coat on top of the bare metal, original primer and body filler, then sand that down, add another coat then sand that down and then i'll be ready for my color right? I'm very new to this process so I don't know the terms and actions to take all that well. So any help / answers / recommendations etc. and product reviews will be greeaatly appreciated. Thank you so much in advance.
