Removing factory undercoating?

Blue · Post by **Blue** » Fri Dec 20, 13 6:47 pm

How do you do it? I've always used an old wood chisel to scrape it off dry, works well enough on flat panels but gets to be a bit of a chore on shaped panels. Any abrasive power tool I've ever tried just tends to smear it about. I wondered if any of you had found something to soften it up a bit without turning it into some horrible tarry gloop...

Nope

A wire wheel on an angle grinder gets rid of a fair bit but it's horrifically messy and really dangerous!
I'm with you on the blunt chisel and a I favour an old fashioned butter knife for curves and a blunt screwy for the fiddly bits!

Seems like a good idea, Drewe, but not sure if they will ship to the UK.

How many tins to do an "A" body???

I started that way and ended up with a gloopy gloppy mess.

They key is the citrus it seems to seep under and really loosen it up , I think any citrus based cleaner would work ,

I bet you can find it over there ,perhaps a commercial cleaning company

Quick, easy and safe removal of undercoats.

Eastwood Under Gone Undercoating Remover aerosol works by loosening the bond of the undercoating to the base metal and allows you to scrape it off, leaves a paint ready surface.

Not designed for use with urethane epoxy or bake on undercoating.

Shake can thoroughly before, and periodically during, use. Spray-apply to a 12" square area and allow to penetrate for 30 seconds to 2 minutes. Then scrape loosened undercoating from surface. Reapply if necessary to remove heavy applications.

NOTE: Will remove paint! Rinse painted surfaces immediately with water to avoid damage. Do not use for removal of baked-on, epoxy or urethane coatings.

£12.25

the trick is not to soften it too much, I've had success with a heat gun and wallpaper scraper as well as a blow torch (held briefly over the area) and wallpaper scraper, also found that one of those wallpaper steam strippers works if you remove the flat plate and just hold the pipe (while wearing a glove of course), scrape it while directing steam at it. It just needs to be warmed slightly to loosen it, get the timing right and it all works well

Soften with blow torch and it comes off nice and easy with a scraper.

Spray/wet with petrol. Leave to soak. Hot pressure washer. Just falls off.

Everyone has a hot tap outside tap next to the cold one like me dont they?

The only problem i found is that my hot water tank is not big enough to do more than about a 3rd of a car at a time.
