Hi Jim:
There are a lot of model AC coatings available and some are translucent, but the type of Monocote I’m thinking of truly is pretty solid. You may be thinking of one of the polyester cloth-based coatings which are usually used to replicate fabric covering on older airplanes and on WW-II aircraft control surfaces. The chrome Monocote is a thermoplastic coating which is not translucent. Having said that, painting the cowl silver first wouldn’t hurt - although it would be important to be certain that the paint adhered very well to the fibreglas.
Back to the motorcycle: I’d simply sand the cowl molding (you’re looking for a smooth uniform surface with no dimples or bumps - not a mirror finish). This is important because the coating adhesive needs something to which it can adhere. Then get the dust off it with a tack cloth and try the Monocote - wrapping the coating around the bottom edges of the cowl by at least 1/2-3/4” to ensure that it stays put. When I finish a part like this - I sometimes seal the edges (which are wrapped around and thus not visible), with glue to ensure that the coating doesn’t come adrift. I’ve got several planes which are decades old - and the coatings are fine - although they don’t live outside everyday and very seldom see rain.
The hot iron will help get it around the compound curves - and you might need to do it a couple of times to get it just right and note that the Monocote film is sort of a one-shot deal. So, if you have start over, you'll need a new piece - but this stuff is dirt cheap compared to automotive paint and the cost is
microscopic compared to real chrome plating.
Now, I haven’t flown in several years, but since Dude asked, here are a couple of photos of my planes. I like 1920-30s racing planes (often referred to as Golden Age aircraft). You are undoubtedly familiar with the famous Gee-Bee Model R aircraft which was very rotund and had tiny wings. There was an entire cadre of racing planes and pilots that were on a very active national circuit. The premier races were in Cleveland OH but they occurred all over the US AND Europe. These contests were extremely exciting with frequent crashes and deaths. One of the aspects of my hobby which is a little different is that I don’t (or didn’t) fly very many foam aircraft. I build them from scratch or from kits - or I buy old models at swap meets and restore them with crash damage rebuilt and often new coverings and markings as well as radio systems, power trains and servos. Anyhow, enjoy!
