TR4A1965 Posted December 17, 2015 Report Share Posted December 17, 2015 When I stripped my TR down I found the wiper wheel box cover plates (See pictures) had mastic around them. I guess this was a waterproof seal to stop water from around the wipers getting back in to the car. I also found the same mastic on the heater hose plate that is also attached to the bulkhead. My guess is, that this mastic was done during a previous restoration a long time ago? Was mastic used in the factory? If so what mastic should I use now? A clear mastic might look better than the black treacle I found? If it wasn't used, is it a good idea in this location? It seems to make good sense to me to put the mastic in place? Best.

pfenlon Posted December 17, 2015 Report Share Posted December 17, 2015 yes its needed without doubt, a good silicone sealer would do, when ALL the old mastic is removed. But others may suggest other types of water sealant. the old stuff was like window putty that never hardened on my car. Quote Link to post Share on other sites
stillp Posted December 17, 2015 Report Share Posted December 17, 2015 If you use a silicone sealer, oil the cover plates before you refit them - you might need to remove them one day! Pete Quote Link to post Share on other sites

peejay4A Posted December 17, 2015 Report Share Posted December 17, 2015 That's the stuff Paul. It's non setting and easily cleaned off with white spirit. Multiple other uses. Quote Link to post Share on other sites
