Original Honda undertray - tatty

[fritzdog]

Good Morning!! I wonder if anyone can help? My project Storm is slowly making progress, am working on the seat area at the mo, and I want to keep the original black moulded plastic undertray. But it's really old n tatty, bits of rubber stuck to it (these mostly come off with petrol) scratches etc. Is there a way of restoring this plastic to an acceptable standard (I know it's only visible from the underneath, lol), maybe shotblasting and heatgun, or is it a dead loss?
Thanks in advance,
Mick

the autoglym black bumper stuff the green gel stuff is good for that kinda thing, takes the black back to a nice new look especially if it has faded a bit.ive used it alot on that kind of thing.just give it a good hot wash first and dry it, if you can get it swarfega truckwash soap is a good cleaner / degreaser but i think its only sold in 5 gal drums.

As for the wear and tear/scratches, I would sand any deep scratches out and then maybe use some kind of polish like T Cut or something to try and smooth things back out. Boot polish works well to bring the colour back too.

Heat gun works on oxidised areas but its also easy to mark the plastic. Myself, I would go with what Carl said because iv'e been doing it that way for a long time and it works.. Flat down any deep marks/scratches with fine paper, and for rough areas or stubborn dirt you could use a fine scotch pad then just buff it all back up... I know Carl only used it as an example but in my experience better than T-cut... farecla g3 abrasive polish, easier, works harder and longer because you can add a drop of water to stop it going dry. Have used farecla many many times to clean up plastic, car door mouldings, plastic headlamps that have yellowed and I could go on and on with examples.. I rubbed a load of deep scratches out of my storm mirrors... polished them up with farecla, you would never of known. As for any normal polish/gels... all good to make pretty but they won't give a long term solution, the flatting/farecla process will cut into the plastic effectively removing the oxidised plastic rather than just sitting on the top masking the problem. Will take a bit of elbow grease and patience but will work.
