Wrangler TJ Rust treatment options

I have just bought a 2002 Jeep Wrangler Sport (4.0L, 5 speed manual). It has rust issues (no surprise there!). I want to winterize it as I live in the North East (read snow, sleet and plenty of salt). The floor pans were OK just some surface rust and two tiny pinholes. I have sanded, cleaned and will apply a coat of either Rust Bullet or Eastwoods Rust Encapsulator. The frame does have flaky rust and surface rust in a bunch of places but no obvious rust holes. I want to put rust proofing coat on the frame and an undercoat to the whole. I thought about using POR15 or spaying on Eastwood Rust Encapsulator, plus Eastwoods frame interior spay stuff but I have no lift area and limited space. Then a friend mentioned just get it done by a shop sooner as winter is nearly here! So, I did some searching online and Auto Rust Technicians in Cranston, RI seems to be the place (or one of them) to go. I got a quote of $600-$700 to sandblast the surface and flaky rust off then apply a coat to the frame and undercoat the whole floor areas etc. Does this seem reasonable and would it be worth it? See attached photos of the frame as it is now. Cheers all

If I were you I would remove the skid plate and look for rust holes. My 99 frame looked great until I removed the plate.

I think 600-700$ isnt that bad when your paying somebody else to do it. But i agree with attempting to unbolt the skidplate and see how bad it is. If the bolts will come out.

Yeah, thanks. I did look around the skid plate area of the frame. But as you say can't be sure until I get the skid plate off and check the bottom side of the frame in that section. The skid plate bolts don't look rusty but are too firm for me to get off with my torque wrench so will need a longer arm. Have WD40 on them including the one attached to the transmission. Leaning towards just getting auto rust tech to sand blast and undercoat. If they see any sections of the frame that are suspect they can use one of there kits to repair but I hope they won't have to do that as it will just up the cost a lot. According to their video on their website and YouTube after they put the coating on they can drill drainage holes. I only had surface rust on the floor pans under he carpet, no holes and have just sanded and wire wheeled that off, removed grit and grease today and will apply something like Eastwood rust encapsulator or rust bullet soon. Thanks again
