rolled roofing using 600 wet dry on my engine shed is not coming out right , I,m using 600 paper and white glue on plastic roof and getting some wrinkles. Is there a better way of getting the rolled roofing look . Ive read about using masking tape and paint but the wet dry texure looks right .Any Ideas ?

Jerry,
Many years ago I used model airplane tissue covering(cut into scale 3 ft strips by 20' long) I used model airplane 'dope' to stick/seal the stuff. It came out quite good - But the 'smell' was bad.
A few years ago I used sheets of 'vellum' I got at Staples - I used 3M spray contact glue to affix it. A much better solution! The vellum I purchased was 16 lb stock - I air brushed it a weathered black after it was affixed to the roof, and then weathered it with Pan Pastel weathering colors.

Year's ago,I used masking tape,sprayed with Floquil Grimy Black, I don't believe,it looked bad,older rolled roofing,did have wrinkles in it,a lot depended on what part of the world,you lived in though..
Cheers,

The wrinkling problem comes from the adhesive that you chose to use. To hold wet/dry sandpaper onto plastic, the glue needs to have a great deal of tack strength to hold the wet/dry sandpaper flat on the plastic, while the moisture penetrates the coated backer paper stock. This takes time, and when the moisture from the adhesive finally penetrates, the fibers in the paper become larger (this is a good thing as having some of the adhesive solids work their way up into the paper, will ultimately do a great job of holding the wet/dry on the plastic.). When the fibers swell up, if the glue does not have sufficient strength to resist that movement, the paper lifts, and you get the joy of fighting wrinkles.
The wet/dry 600 grit sandpaper is a good way to get a rolled roofing look. The grit is small and gives great texture to the roof. For this type of work, my preference is a product called Ultimate Tacky, from a company called Crafter's Pick, in California. You will find folk with other equally valid preferences- it is one of those not so open secrets that all white glues are not alike, so read labels carefully.

What I've done most recently is to use paper glued to cardstock with an archival quality glue stick intended for scrapbooking. The adhesive is strong and stays solid.
If you have a substructure made of plastic, you can laminate the cardstock onto that with something that bonds to dissimilar materials (Weldwood contact cement thinned 50/50 with lacquer thinner works well). You could also skip the cardstock and laminate the rolled roofing directly to the styrene with the contact cement, although this can be harder to control. In neither case will the adhesive cause the roofing material to wrinkle.
There are areas of rolled roofing on the grain elevator at left made from 20# printer paper laminated directly to styrene with the thinned Weldwood cement. I built this structure about 20 years ago and it's survived two moves and three layouts. All the siding and roofing materials were attached the same way and nothing has come loose over time.

IMHO: Sand paper is too thick in HO to make decent rolled roofing.
I use plain old construction paper glued down with Aileen's or similar adhesives. Watch out for curling or crinkling with water based glues such as Elmer's... I then use weathering powders to give the roof that "lived in" look.
Construction paper roof.
I have also used paper corrugated paper roofing. Glued in a similar method, no powders.

thanks Guys ,I didn't get the last two post till I was done, but to conclude I did use the 600 wet dry ( Cause its what I had) and no I did not use scale widths or lengths ,just what looked good two my eye , I took the advise of others and used a type of contact glue" Plilobond " @ lap joints (again what I had) and used good ole "gorilla brand super glue" for the field ,brushed on . and it seems to have worked great.
It is better than the flat plastic ? roof , and the ends and sides of the paper need touch up as the whitish backing is noticeable .I well try and post a Pict ,that well tell the tale on being plausible or not ..
the black paper Idea would of been better or more scale ,next time ...thanks to all...Jerry
I'll have to check out sanding film..
I use a felt tip pen on the cut edges of white backed roof materials before gluing to color them black so the white doesn't show.
Jerry glad it worked out.
yep ,wish I would of caught it before, I will do the gloss black and fine brush for the tar strip look if it bugs me.... Oh and the posted picts of you guys work are very nice and helpful ...Jerry
