Royal Coachman Dynaplastics Hard top
Posted by: exfed12825

I bought a Royal Coachman Dynaplastics removable hardtop last year. I've been checking this top over for paint and installation, it looks to be vinyl covered but may have the grain molded in, is there anyone out there that knows anything about these tops ? I want to paint it to match the paint scheme on my MG, if the grain is actually molded in to the plastic I have no problem with just leaving it and painting over it. The other thing I need is new gaskets, I have been searching the net for replacement seals and have found that Royal Coachman went out of business years ago and haven't been able to find out a whole lot of information. I sure could use a little help on this before I start to tear into it and screw something up.

Hi Tony,
I found a Bermuda Classic hardtop for my MGB... and all of the rubber seals were shot.

Front seal is standard MGB and easy

window seals again, were easy... right out of V/B or Moss... bought mine on EBay

6 months buying and trying anything close to seal between top and body... got a huge box of failures. Found a retired owner of high end upholstery shop who solved (for me) with suggestion I buy AUVECO part # 4746. It was a 50 ft roll but local supplier "broke a box" and sold me 15'. Think it was actually a door seal for a 1958 and newer Chrysler!

You might also check Steele Rubber and other major suppliers.

Good Hunting!

Give good old JC Whitney a try.
They carry a large selection of universal weather stripping. With side profiles and measurements.
I've used them on many occasions and the quality is good.
It always amazes me when I look through the catalogue (so does waking up every morning, but that's something else altogether)
My dad owned a good old fashioned hardware store when I was growing up.
Right down to the creaky worn wooden floors and the bell on the front door.
JC reminds me of that.( wiping away a small tear)
It's time for a scotchy scotch isn't it?

Hi tony,
Do you have a picture from that hard top? I think I have the same problem. Vinyl covered or grain imbedded. But I think it is vinyl covered. Need rubber gaskets too and the plexi for the sides.

They were not vinyl covered. The grain is moulded in anf the black surface is gelcoat. It's not hard to sand smooth but the fiberglass has tons of pin head sized air bubbles so you have to fill those before painting. I have mine sanded and ready to paint - just need the time to actually spray it!

Also, check the fasteners where the front clips and side hold downs are. They were steel screws that go into captive nuts in som eood that was formed into the top when made. On mine, that wood had rotted out so I ended up having to cut them out and fix. I replaced the wood with steel flat plate drilled and tapped so I don't have to worry about wood rot again.
