Hi

Both my subframes are thoroughly degreased, repaired and have just the original black coating on them, light/surface rust in places but nothing serious.

What have other people paid?

Is powder coating best option?

I've no problem grafting to DIY them if I can get it good enough.

Powder coating is good until you get a chip then it rusts from underneath.

Its been a while since Ive had something powder coated but think £30-50 each would be about right.

I had my rearsub blasted to take off all the rust cost 70quid. Then sprayed it myself and its...just ok.
The front i had blasted cleaned and piwder coated (at a different shop) and the result is SO much better.
Cost 100.
I have found lots of these shot blasters/powder coaters seam to make up prices as they go along (or what ever they can get away with) so try and find several in your area if you can and compare prices, but recommendations go along way.
Might help to know where you are in the counrty.

Hi thank you, yes I think you're probably right!

I'm between Aylesbury and Bicester so Buckinghamshire Oxfordshire area is good.

Been quoted £200 blast only for the pair by a contact I was given locally which I had hoped would be the cost including coating.

Doing this job right now too. For shot blast and powder coat including a zinc primer was looking at between £60 to £100.
Decided to get it shot blasted and paint myself with epoxy primer (jotun87)
Haven't found a shot blaster though

With things like this a word of mouth is best in finding a reliable shop. Once the frame is coated up you cannot tell what is underneath i.e. how well was it blasted?. The thickness of the coating is also important and does vary. It all depends how diligent the person doing the work is.

I have just had a lot of blasting/powder coating work done by a small firm where there is no hiding place if the job turns out poor. The smaller guys tend to do a better job as they have their reputation to protect.

You could ask for pictures as the process progresses to reassure you.

I used a satin finish powder coat, it gives a manufacturers "look" .

For a rear subframe to be blasted only (no coating etc), I paid just 20 pounds +VAT last week. Was then DIY painted in rust preventative primer and some 2-pack black topcoat, a local specialist is now getting it fitted up to my car for me. I was offered a blast+powdercoat option by the finishers for about 50 pounds but turned this down in favour of getting it painted myself, powdercoating looks nice but really doesn't seem suitable for subframes as others have mentioned.

I got my rear subby shot blasted for £20 recently, then used epoxy primer and a few coats of black (can't remember off the top of my head what it was!).

 

I wouldn't go for powder coating as once it's chipped / cracked it will rust under the coating without you knowing, plus you can't repair powder coating without starting again!

 

Go for the paint option, it's easier to maintain!

Thank you all for the replies.

On your advice I'm going to bin the idea of powder coating in favour of epoxy I'll apply myself.

I'll see if I can find a more economical blaster, if not I'll prep by hand.

Thanks
Paul

I had mine blasted, then zinc coated followed by gloss black powder coat, I then filled all internal cavities with dinitrol, much easier than my previous resto when I wire brushed them and applied a phosphate primer followed by 2k gloss, both have lasted well but I think the powder coated ones are more durable.

I managed to get the rear done for £30 (Gemini shot blasters in Hartlepool. Highly recommend.)
I've applied epoxy primer (Jotun,87) and absolutely chuffed with the results. I'm overcoating with engine ename, the job looks great so far. I also sealed the seams with PU just as added protection and will dynax the cavities later

Update, I've agreed £120 for both frames with etch primer.

He's also doing the shell including engine bay, inside and underneath for £500 etch primed.

So, overall I'm happy, frames a little expensive but total is good for me.
