someone tell me in beginner talk what yall are saying! if i can cut down on one stage of paint thats a good thing. my truck will be in primer for a few months and outside covered cuz of not having room to do my other metal work. the cab is in my 1 car shop the paint is good on the cab but i have some mods done thats down to bare metal. the bed is just about bare metal after i get done cutting on it. the inner fender wells are bare metal so everything needs to be sealed so it will not rust from setting. i dont plain to paint the truck for a few months and i live in houston tx kinda close to the water.
im learning all the paint stuff i can on here and yall have been a big help. the guy thats painting my truck likes PPG stuff but im buying all the paint and doing the body work myself. now the base is chromobase but i got a price on the blue im using and its $680 a gallon lol.. so thats up in the air..
The first thing you need to do is to protect your bare metal from the elements..,and a good epoxy primer that uses a catalyst (hardner) will do that for you. As I have suggested a sandable epoxy primer would be the best way to go...Now, SPI has been talked about and recommended by numerous individuals. I have not tried it yet, but, will shortly. This primer, from all the research I have done and from what I've been told sands very well and does have good build properties (it goes on nice and thick, sorry about the () but I'm trying to put everything in a way that you can understand it). Picking your primer should be your first order of business and in reality you should have had it on hand before you started metal working and making body modifications...Not trying to be rude, just stating a fact.
Again as I mentioned PPG's DP epoxy line works well but it's not a sandable primer and needs to be top coated with a high build 2K (2K means 1) primer and 2) hardner). This system works well but it does require 2 different products whereas a sandable catalyzed epoxy primer only requires the one product. Once you have your bare metal covered with the epoxy (and say you are using the sandable epoxy) you can start to block sand your truck to ensure that your panels are straight. If your using Dupont's Chroma Base, finish sanding in a bare minimum grit of 400 grit dry or 600 grit wet...After all the straightening of panels is complete (by block sanding) you will be ready for paint...If your using Chroma Base and it's $680.00 a gallon, PPG, RM, House of Kolor, or whatever will all be in the same ballpark, give or take $100 or $300...depending on color, pearl content etc...(reds are the most expensive)...I know that $100 or $300 sounds like quit a jump and it is but, how much are you spending to get your truck into a magazine...if it cost you $25,000 or $40,000, $300 in the scheme of things shouldn't be a deal breaker...if it is, then you may need to lower your expectations...again, not trying to be rude, just explaining the way things are (the last truck I did had over $2,500.00 in paint material alone and I haven't seen it in a major publication, not to say that paint alone will get your truck in a magazine, just showing you what's involved).
So, first order of business...pick your primer, clean up your bare metal by sanding with 80 or 120 grit using a DA (Dual Action sander) and get it on your bare metal.
When you have that done and if you need more step by step information, just ask and I'll be happy to help.
I hope this answers your concerns.
