Cleaning/removing underseal
I've got to make some serious GRP repairs on one of my rear arches (big hole),m but first need to clean off a thick layer of black sticky
undercoat.
Anyone any suggestions?
Tried with Gunk and engine degreaser, but that just made it more sticky.
White spirit seemed to work, but took me a couple of hours and 10,000 rags to remove a small square.
Anyone any better suggestions?
Thanks,
Pat...

Try using a pressure washer - it is suprising what these things remove ...... it destickered my wife's CRX without trying

I reckon the J&L steam cleaner would work a treat. See the ad's at your local Woolworth's stores...

Why did you put that poo on in the first place. Was it to stop you guards rusting If for impact protection better with Gelcoat mixed with wax.
Acetone inside guards and paint thickly with gelcoat. Colour can be added if needed.

I bought a pair of crash damaged rear wings which were already undersealed.
Managed to remove most of it with white spirit and 200 old t-shirts - nothing else seemed to work!
Roughed the back up with 80 grit and severely scored with a stanley knife.
2 full flat layers of matt curing as we speak.
Just got to pick all the broken bits off gel coat from around the hole on the other side in a few days and then fill/sand scenario.
Just wondering if it might be easier to start filling the hole with resin and tissue to level it out more rather than filler?
Cheers,
Pat...

Yeah resin and tissue is stronger aint it.Or filler with chopped strand.
" Roughed the back up with 80 grit and severely scored with a stanley? "

Petrol is pretty good at dissolving underseal - could be worth a try if you're feeling brave Pat...

That's what you are supposed to do, full thickness chunks of filler can easily crack around the edges.
