Chemical dip to strip powder coat from 531 frame? With Chrome? Experience?

Hi, I am looking to remove some cruddy powder coat from a thin walled 531 frame that has chromed rear stays. All shops I've talked to recommend dipping to remove PC instead of sandblast. My question is about dipping/stripping and the impact on the chrome?

One shop here said they have done it ("do it all the time") with no impact to the chrome. Another said they hadn't done it, but feared it would somehow cloud/dull the chrome finish?

Anyone have experience with stripping and chrome?

Paint stripper can remove PC and it will have no effect on chrome.

I haven't done it, but I feel way safer doing a chemical strip than blasting.

Ditto, paint remover works on organics. I've done one on a Fuji "The Fineset" which was fully chromed. Quite a mess, took several dips to do the job.

I own a powder coating shop and have stripped many PC finishes from chrome items. No impact on the chrome afterward. Blasting off PC is really only for shops too cheap to invest in the vat and stripper. It's fiercely expensive when I need to refill the vat, but the alternative, which is blasting, is too harmful on the substrate because I have to dwell much too long with the blaster to finally get all the PC off. That leaves the substrate damaged and eroded.

The chemical I use in my vat (as well as pretty much all decent PC shops) is Methylene Chloride. We buy it in 55 gallon drums for economy and it's full strength. Over the counter paint strippers usually use methylene chloride as the active ingredient, just in much lower concentration. They work as well if you're patient and understand it's going to be lower strength than your local PC shop stripper is.

How much would you charge to just strip a frame?

Find a local shop that does a lot of car wheels. They'll have a good fresh batch of stripper and shouldn't run you over maybe probably 20-30 bucks I'd guess. The trend is to "murder out" new cars and trucks so any shop that coats cars wheels will be well equipped to strip powder off since they do it on the wheels before they coat them black for the customer.

Thanks for the tip!

Thanks for all the good feedback. Good to know it's safe on the chrome. I got quoted 40-60 in my market.
